skynx Posted December 23, 2012 Share Posted December 23, 2012 am on my third grow of supercritical. Hydro system all in hydoton medium. 1000watt light and 2 gal bucks. Drip system. Using gen hydro 3 part micro plan. Been using same nute mix for years but last two grows of supercritical go all yellow on me by finish. This time i added co2 system an probs showed 2 and a half weeks into flowering. Fan leaves get light green and yellow splotches that turn brown inside eventuly an leaf will go all yello eventuly. Thought over fert but cut that back 4 days ago an now all goin light green. Seems like calcium or manganese defficincy but hell. Anyone expirienced this with this strain? All leaf edges seem to rise up in a opposite canoe paddle form. Goin with a deff an gonna kick in some cal-mag an see what happens. Ideas anyone? They hungry for nitro?

Dust Posted December 23, 2012 Share Posted December 23, 2012 are you bottles still good? i had this problem on the end of life of my bottles was not hydro but i guess it would do the same in hydro Beside that, show us a little picture of the problem it will help members to identify your problem I move your thread to informary here is only for the grow reports Good luck keep us updated Link to comment Share on other sites More sharing options...
skynx Posted December 23, 2012 Author Share Posted December 23, 2012 cool thanks man. Was thinkin it could be that but all my nutes are pretty new. Pretty much buy them by the quart so they go fast. I get cold temps but have been running a infared heater in the room to keep it at atleast 68 degrees. Sorry dont do celsius lol plan on finishing this batch an ditchin the strain.

skynx Posted December 23, 2012 Author Share Posted December 23, 2012 supercritical is what whitewidowXbigbud an somethin but was wondering if they want extra nitrogene? Thought the big bud just sucked that stuff up? Link to comment Share on other sites More sharing options...
skynx Posted December 23, 2012 Author Share Posted December 23, 2012 plus the new clones I have comin up an watering with same nutes look excellent. Seems they might have the edges rising up a bit to though. Use shallow well water an wonder if is something to do with that. Is stressin me out lol been here 3 years an never noticed any of this before.. Though will freshen the nutes soon to be safe Link to comment Share on other sites More sharing options...

flowers to the people Posted December 25, 2012 Share Posted December 25, 2012 Hi mate,Cannabis is a plant that varies enormously in all its attributes. This includes nutrient needs - Cannabis still needs as much nitrogen during flowering as it does phosphorus. In general, as it does vary from strain to strain, during flowering cannabis requires high levels of nitrogen, as well as calcium, potassium, and magnesium.You could either try a higher Ec , or else give your plants a diet supplemented with increased levels of these nutrients.take carejohn Link to comment Share on other sites More sharing options...
bigred Posted December 26, 2012 Share Posted December 26, 2012 how are you testing your water sounds like a bit of calcium magnesium booster might be a help. do you have a brix meterthey measurer the sugars in your plant leaves very handy as it helps diagnose problems fast . it is a must have to usewith co2 as it speeds up growth so deficiencies are hard to catch before they set in . by using a brix meter during floweringand to get the ideal sugar levels in the plant is hard to learn and explain but once you get the jist of it your plant's willreward you with sticky goey tricromeshttp://en.wikipedia.org/wiki/Brix Link to comment Share on other sites More sharing options...
skynx Posted December 29, 2012 Author Share Posted December 29, 2012 well it seems it maybe some damn bugs in my roots... See the worms in my flush water today. Frickin strange i wouldnt see one till the beginning of week 5 though. Specialy seein i had flushed them twice 6 days ago. Hard to think aanything else tho cause i see them. Hell. Anything i can run through to kill them this late? Clear bodie with little black head. Seen them before but not in these numbers. Link to comment Share on other sites More sharing options...
skynx Posted December 29, 2012 Author Share Posted December 29, 2012 would like to believe they came from a friends water source but i only used a gallon or two of that like three days ago an now there are a shit load of the worms or watever so they musta been eating on roots before then. Not nearly enough little black flies around for them to be that. Had to come up with my well water i am guessing.. RO water system in a week or two. No cash till then tho. Any flush idea be cool though. Gonna go search an all that for now. Peace Link to comment Share on other sites More sharing options...
skynx Posted December 29, 2012 Author Share Posted December 29, 2012 fungus gnat larvae forsure. Dang it! Temp an all that just wasent right for me to notice or them to thrive though i guess. Anyways i feel good knowing what the heck now. Anyways i like two ways mainly for the roots. Either a hot water bath? Or peroxide treatment? Anyone have info on these? Hot water selfexplanatory but how hot could i get the water for a quik flush? Peroxide sounds the way to go. Read one that someone said 4 parts water to 1 part peroxide. Though wonder what percente peroxide they meant. 3% easy to get but how much more do ya wanna water that down? Could maybe get foodgrade stuff at 35% and would probably be the best but not sure if 4 to 1 would dilute enough. Will explore for more info. Any suggestions be welcomed though. Thanks.

bigred Posted December 29, 2012 Share Posted December 29, 2012 neem oil can work get some and mix it with a peroxide treatment try organic methods before moving to chemicalsbut your local nursery should have a toxic alternative but will put heavy metal's in your budsedit i would stick to the 3% in peroxide but there are hydroponic ones which are 6% and contain colloidal silvernot to stong as it will cause you a whole new set of problems Link to comment Share on other sites More sharing options...
skynx Posted December 29, 2012 Author Share Posted December 29, 2012 yeah I hear ya. Gonna call a place or two tomorrow. May go with a plant or two for the fliers. Sundew plants and or a pitcher plant. May try a weak peroxide mix or a hot water flush. Also the mosquito dunks sound alright? Link to comment Share on other sites More sharing options...
Dust Posted December 29, 2012 Share Posted December 29, 2012 on root problem i often hear the use of peroxyde is pretty good, and i don't think it can hurt your plants anyway, but for the larva i don't know if it will work.Wait till the expert in root problem pass by Good luck Link to comment Share on other sites More sharing options...
Canabuz Posted January 8, 2013 Share Posted January 8, 2013 Hey bud, sorry to here about your girls getting bugged out, let me know how you were able to handle your problem Link to comment Share on other sites More sharing options...
flowers to the people Posted January 16, 2013 Share Posted January 16, 2013 hi mate,the bugs feed on the root hairs and eventually do your plant a lot of damage. They also can infect your plants with root rot. There are a number of organic pesticides that will help, but the main thing is to cover the tops of the pots with expanded clay, and that way the pests can not reach the moist medium to lay their eggs. The lava love potato, so put some slices of it on the top of your medium and wait a day or two and then dispose of the potato plus the maggots.They are a problem in a lot of gardens, and though a mature plant can cope with them, a small plant will be damaged by them. As well where they consume the roots, the roots are left vulnerable to root rot. There are some friendly bugs that eat the lava also, and these can be introduced to feed on the maggots.It is not a major problem but one you should get on top of as soon as possible.good luckjohn Link to comment Share on other sites More sharing options...
Pi2 Posted January 16, 2013 Share Posted January 16, 2013 Hydrogen Peroxide and HorticultureHydrogen Peroxide (H2O2) is a clear sharp smelling substance very similar in appearance to water (H2O). Like water it is made up of Hydrogen (H2) and Oxygen (O2), however H2O2 has an extra Oxygen atom in an unstable arrangement. It is this extra atom that gives H2O2 its useful properties. H2O2 has been used for many purposes including cleaning, bleaching, sterilizing, rocket fuel, animal feed treatment and in addition many miraculous claims about its health benefits have been made. This article isn't about any of these; instead it will concentrate on horticultural applications. H2O2 is of great use for both hydroponics and dirt/soilless gardening.What Does Hydrogen Peroxide do?H2O2 is an unstable molecule, when it breaks down a single oxygen atom and a molecule of water is released. This oxygen atom is extremely reactive and will attach itself to either another O- atom forming a stable Oxygen molecule or attack a nearby organic molecule. Both the stable and O- forms will increase the level of dissolved oxygen. This is the method by which H2O2 is beneficial. Pre treating the water supply with H2O2will drive out the Chlorine many cities use to sterilize it. This will also degrade any pesticides or herbicides that might be present as well as any other organic matter. Well water can be high in methane and organic sulfates, both of which H2O2 will remove. Many disease causing organisms and spores are killed by Oxygen, the free Oxygen H2O2 releases is extremely effective at this. H2O2 will help eliminate existing infections and will help prevent future ones. It is also useful for suppressing algae growth. The free Oxygen atom will destroy dead organic material (i.e, leaves roots) in the system preventing them from rotting and spreading diseases.Over WateringRoots require Oxygen to breathe and low levels are the main cause of almost all root diseases. Both soil and hydroponic plants often fall prey to the same syndrome although it is rarely recognized as what it really is. Hydroponic crops often fail due to "root rot" and soil crops succumb to "over watering." The real cause of both these problems is a shortage of Oxygen at the root zone. In a soil system the soil consists of particles, a film of water on the particles and air spaces between the particles. When too much water is put into the soil the air spaces fill with liquid. The roots will quickly use up what Oxygen is dissolved in the water, if they haven't drunk enough of the liquid to allow air back in to the soil spaces they will stop working. In this situation roots will start dying within twenty-four hours. As the roots die the plants ability to drink water and nutrients will decrease, this will cause symptoms of nutrient deficiencies (mostly pale, slow, weak growth), and strangely they will start to wilt like they don't have enough water. It is easy to make a fatal mistake at this point and add more water.In a Hydroponic system the cause is a more direct simple lack of oxygen in the solution; this may be from inadequate circulation and/or aeration. High reservoir temperatures also interfere with Oxygen's ability to dissolve in the water. Temperatures above 70F (20C) will eventually cause problems, 62F-65F (16C-18C) is recommended. The same symptoms will appear as with soil plants but you can also check the roots. Healthy roots should be mostly white with maybe a slight yellowish tan tinge. If they are a brownish color with dead tips or they easily pull away there is at least the beginning of a serious problem. An organic, ‘dirt like’ rotting smell means there is already a very good chance it is too late. As roots die and rot they eat Oxygen out of the water, as Oxygen levels are even further depleted more roots die, a viscous circle may be well under way. Reduced Oxygen levels and high temperatures both encourage anaerobic bacteria and fungi. The plants may still be saved but you will have to work fast.How Hydrogen Peroxide prevents root rot/over watering.When plants are watered with H2O2 it will break down and release Oxygen into the area around the roots. This helps stop the Oxygen from being depleted in the water filled air spaces until air can get back into them. High Oxygen levels at the roots will encourage rapid healthy root growth. In a Hydroponic system H2O2 will disperse through out the system and raise Oxygen levels as it breaks down. Strong white healthy roots with lots of fuzzy new growth will be visible. This fuzzy growth has massive surface area allowing for rapid absorption of the huge amounts of water and nutrients needed for rapid top growth. A healthy plant starts with a healthy root system.How to use it.H2O2 comes in several different strengths 3%, 5%, 8% and 35%, also sold as food grade Hydrogen Peroxide. The most economical is 35% which we recommend be diluted to three percent before using, as at this high concentration it can cause damage to skin and clothing. When working with food grade H2O2 it is very important that you clean up any spills or splashes immediately, it will damage almost anything very quickly. This is extra important with skin and clothing. Skin will be temporarily bleached pure white if not washed cleaned. Gloves are strongly recommended when working with any strong chemical.Food grade H2O2 can be diluted to three percent by mixing it one part to eleven parts water (preferably distilled). The storage container should be opaque to prevent light from getting in and it must be able to hold some pressure. If three-liter pop bottles are available in your area they are ideal for mixing and storing H2O2. There are twelve quarter liters (250ml) in three liters, if you put in one quarter liter H2O2 and eleven quarter liters (250ml) water in the bottle it will full of three percent H2O2 and the bottle can hold the pressure that the H2O2 will generate. Three percent Hydrogen Peroxide may be added at up to three ml's per liter (2 1\2 tsp. Per gallon), but it is recommended that you start at a lower concentration and increase to full strength over a few weeks. Use every watering even on fresh cuttings. For hydroponics use every reservoir change and replace twenty-five percent (one quarter) every day. Example: In a 100L reservoir you would add three hundred ml's (3%) H2O2when changing the nutrient. You would then add seventy-five ml's more every day.Where to get it.35% food grade: called food grade because it has no toxic impurities. Of course your local hydroponics retailer, whom you can locate over the web.(there may be shipping restrictions on high strength peroxides).3%5%, 8% Can be found at most pharmacies, prices start at a less than a quid for a one hundred-ml bottle that will treat one hundred liters.What to do if you already have root rot.In Dirt:Use peroxide water with an anti-fungicide and a high Phosphate fertilizer (9-45-15, 10-52-10, 0-60-0) for root growth. Or any other product with rooting hormone dissolved in it is helpful in regrowing roots and is strongly recommended. Water heavily until liquid pours out the bottom of the pot. This sound like bad idea, but it flushes out stagnant dead water and replaces it with fresh highly oxygenated water. Don't let plants sit in trays full of water, the soil will absorb this water and stay too wet. Don't water again until the pot feels light and the top inch or two of the soil are dry.In Hydro:Change your nutrients. Add H2O2 to the system. This will add oxygen and chemically eat dead roots. If roots are badly rotted and can be pulled away by hand you should pull them off. They are already dead and will only rot, causing further problems. Add a fungicide to kill any fungus that is probably present in the rotted tissue to prevent it from spreading. Increase aeration of the water, get an air pump and air stones, or more of them, for the reservoir. An air stone under every plant is usually very effective, but will require a larger air pump. Models that will do from forty to four hundred stones are available. Decrease the reservoir temperature, oxygen dissolves better in cold water and disease causing organisms reproduce slower as well. A good temperate range is 62F to 65F; anything above 70F will eventually cause a problem. It is also a good idea to remove any wilty plants from the system and put them on a separate reservoir so they don't infect plants that are still healthy.SummaryThe key to big productive plants is a big healthy root system and Hydrogen Peroxide is a great way to keep your roots healthy. It is a must to ensure the biggest best crops possible and to increase the chances of your plants thriving to harvest. Peroxide users will rarely lose plants or crops to root disease and will harvest larger and more consistent crops.Link: http://www.quickgrow.com/gardening_articles/hydrogen_peroxide_horticulture.htmlMay help someone...Peace Link to comment Share on other sites More sharing options...
