There was another similar question, I responded to earlier.

 

There can be many reasons why your plant leaves turn yellow:

 

1. Lack of sunlight. If your plants don't get sunlight at all, you should consider repositioning them. Like in humans, sunlight is an important factor in the growth and developement process of a plant.

 

2. Root issues/nutrients. You should try checking, if you'd need to add fertilizer or repot your plants. Sometimes the roots get too compacted within the pot and this can also lead to oxygen issues and the roots sticking out from the bottom of the pot.

 

3. Too little water. Self explanatory.

 

4. Insects. You could try and look if there is a pest problem on your plants and maybe use "Neem Oil" (I never used it myself, but it's from a sout asian tree and completley natural pesticide).

How i wish helping growers would be as easy as to help myself.
Could be many reasons and very hard to help without a background story on what you done up to this point.
Usually when a flower turn yellow a few days after flowering it´s as simple as.
To Much water OR lack of right feed as in nutes.

I had that problem when I put too much feeding( leaf become crispy, not so soft anymore) and then  PH was too low...because of N..

EC pen in operation???

Any pics...?

Keep Growing!

IT'S now the end of the first month of flw. i grow in gronest 16 L. soil with guano at witch i added perlite and coco., an equal mix. i watter every 3 day's about 2L/plant, the soil is usualy dry when i watter. and every other with fert.  I use a mix of organic  Guano fertilizer with NK 2.5-6( the soil is the same brand as the fert. the fert is made to be absorbes the best by this soil) and i recently added an organic tomato fertilizator''green future' with seaweed with 4-1-6 i think it is a litle bit too much N. but i only used 2 times now. the yellowing of the tips and leafes curling up started before. i think for the first month of flw. the plants are a little poor! and a tw plant is showing what i think are sighns of heat stres. the constant room temp is 27+- and Humiditi 45+- 1,2 degrees i have 3 tw. and 2 BBK the BBK are much smaller and a branch on one of them is really burnt up! . i would gladly accept and love some advice!! ( exc. the english mis.) thank you and have a great day! PACE!

Tips of fan leaves clawing downwards is one of the classic signs of Nitrogen toxicity.  It's not too drastic unless the leaves begin to yellow, starting at the very tip.

Other Pictures above Show edges Curling upwards.  That is classic sign of heat stress.

 

You describe that your plants are already X-number weeks in flowering and you are still giving Guano and other Nitrogen-containing additives....  That may be your Problem.

Generally, when flowering starts, that is when Nitrogen feeding should be cut to a Minimum, and the feeding for flowers should be slowly increased (phosphorus, topping micros, etc.).  Also at the Switch-over to flowering, it is sometimes advisable to perform a flush to clean-away the excessive Nitrogens and the unwanted salts that have accumulated during veg, so that the flowering Phase can begin afresh.  Overwatering (which can lead to root-rot) sometimes Looks like N-toxiccity.  Be sure to allow the soil to dry a bit between watering. MJ roots Need to have Oxygen...

 

You are in soil, so you don't Need to Keep adding so much Nitrogen anyway.  The soil is your buffer and most likely either has already or retains more than enough Nitrogen for the plant.  (If this were a hydro-grow, then you would have to be more attentive to keeping Nitrogen/Nutrient Levels exact.)

 

I suggest for you to do a bit of reading about the LifeCycle of MJ and the nutrients that MJ Needs at the various stages of its life.

Such Information is available at many places in the Internet.  The Servers and Providers of these Informations change from time to time, so I don't have any direct links for you.  But you will find a wealth if Information when you perform reasonable searches.  Do the Research.  You will be richly rewarded for your efforts.

Search for things using many combinations of search words like:  super soil for marijuana, nutrient requirements for marijuana, importance of pH for marijuana, pH and nutrient uptake for MJ, search using your own words, be creative, and don't give up.  Along the way you will certainly discover other words and word-combinations that yield even more Information.

Sometimes some answers can be found by searching similarly on Youtube.  Give yourself time to search and absorb the info.  Have fun while doing it.  I know that I did.

Also there is an excellent library of Information on the diseases and pests for MJ.  Search for it under "diseases of marijuana".  You may find several different Versions, many with Pictures included.

 

Each time you find Information that is especially useful, download it if it is possible OR copy and paste it into your WORD document and save it in your own library on your PC or on a Memory stick, so that you will always have that Information at your fingertips.

 

Good Luck, Have fun.  Really...

By the way, if you havent seen it before, a rather fun presentation of how to create a homemade hydroponics Setup is found on Youtube.  Search for "Mr. Green" and "I Grow Chronic".  13 Chapters Long, each about 15 minutes.  And entertaining.

 one of the classic signs of Nitrogen toxicity

 

in my led box it is signal of low phosphor.

P.h 5.5 to 6.4

and flush your plants with 5.5p.h water at least once a week

On a side note, how warm does it get in that tent with the ballast inside the tent?
