Trying something different with Bi. Instead of defoliating, I'm leaf tucking where I can. Hopefully this will shock/delay the plant less. The middle main stem fan leaves are quite large. I've tucked, with plant clips, those four pairs (8 very large leaves) of those large leaves to a stem three nodes down. Light can penetrate better, and the leaf is still attached to the plant so that plant can extract nutrients / dump more toxins in it, and frankly, they get some light. Seems to me that cannabis plants try to get toxins/waste out of their roots first, and when they can't they dump them in the oldest leaves which are the main stem fan leaves (not necessarily the lowest leaves on the plant). While those leaves can be dumped into, I don't want to remove them or the plant will start dumping in the next oldest leaves. I'm pruning any 2nd tier side shoots that come off main side shoots, up to 2-3 nodes along. I think I am going to have lots of stems, so just want cola's on the end and not much growing down below or middle of stem. Happy Growing!

Thanks. I've been amazed, since it was my first proper grow. I am hoping for similar results from my White Rhino. Happy Growing & Smoking!

M=74[5], 3=73[5], Tri=66[6], Bi=67[9]. 59 DAYS LEFT. (large number = days since breaking soil; [days since 12/12 flip]. All plants showing lots of pre-flower double-pistels. Bi is 49cm tall; Tri is 47cm; M is 29 cm, and 3 is 27cm. They're all about the same width as they are in height. Mostly long chunky leafs, with some ~15cm long. Some slight signs of nute burn on the tips of some leaves (yellow), mostly on newer growth. Some necrosis and chlorosis on older main stem fan leaves. Nothing that's worrying me, indeed it's interesting to see what the plants do with a slight excess in nutrients/toxins, ie, what it seems to do with them. I've taken some clones from the bottom of the plants, ie, pruned and put the clippings in some rooting powder then into Rootit! sponges - lets see what happens (I have never attempted to create a clone before). I'd normally compost any clippings, but I figure if they survive, the weather outside will be conducive to their growing in a month or so. Had an issue Sunday morning with temps getting to 100c for about 3 hours. Some slight burn on a few top leaves, but hopefully nothing too bad and permanent. My tent smells like a bakery in the morning with a very yeasty smell coming from my tent. That'd be the CO2 generator I made. Extractor fan is not on during the night to help with humidity and to keep the CO2 in the tent. Still experimenting as to when it needs to come on. Next purchase when money allows will be some kind of controller to turn stuff on when temps/humidity reach certain values. If you remember, when I flushed Bi and Tri on 22nd March I wrote, "Had ~3.3l of run off for both, so will keep that aside for later." My reasoning for this is different to @jan.gh who has written, "In my opinion it will not wash out the BioGrow / BioBloom since it is slow release and not watersoluble " My reasoning is that some of the ingredients ARE water soluble, it says so on the packaging's. Both the Potassium and Phosphorous elements in BioGrow and BioBloom are stated as "soluble in water". I have tested the nearly two week old runoff. Same ppm as originally (~1800ppm) and ph 7.6. So I have diluted it down to 340ppm with a ph of 6.1 and watered Bi & Tri with a litre each. Hopefully any water dissolved PK will get back into the media. I'll edit in pictures to this post later this afternoon. Edit: This is Tri. LST'd with nice node spacings & stretching. Happy Growing!

Hi growchaote, Salt residues from plant waste will cause the media ph to rise, and thus the run-off. What coco are you using, as not all coco's are created equal.

First little pistels on Bi Happy Growing!

It does look like powdery mildew to me, but I'm certainly no expert. I've read that a lot of these leaf molds can be combatted with baking soda & lemon. Me, on a large plant I would chop off the badly effected leaf petals (not the whole leaf if I don't have to), and then spray with a baking soda/lemon juice solution and wipe each leaf with a sponge, and spray again (trying not to get liquid into the pot from the splash from the spraying). On a small plant I would be tempted to swish the whole above ground part of the plant upside down in a solution of baking soda & lemon. Hope you find a solution!

63 days (9 weeks) until the end of the competition. All four WR are now on 12/12. M & 3 where flipped last night with no extended dark period. They will be staying in their 11l pots as a test vs my usual 46l final pots. No more hot-swapping for the WR. The four plants are on 12/12 so they get the big tent. DK & WB are moved to a small room (with the 135rw LED on from 7pm-1pm) and then moved to the big tent at 7am. M was defoliated and pruned of small shoots & leaves, so was 3 to a lesser extent. Bi [Day 5 of flowering] was defoliated, pruned of lower shoots, and LST'd. Tri was defoliated a lot more than Bi down low and inside, with four of her small stems into Rootit sponges to see if they'll make clones. The defoliation consists of removing some lowest main stem fan leaves and some lower pruning of the stem shoots' lowest leafs & shoots. I've defoliated/pruned now so the plant can concentrate on forming pistils on the sites I want; and so there are no dark places in the middle of the plant for mold/pests to make their home. In week 2/3 of flower and I'll select which side shoots to keep and which to chop off for additional clones/compost. Foliar spray has been changed to Rain Water (25ppm). There some excesses showing on some of the older stem fan leaves on Bi. I suspected this might happen as BioGrow & BioBloom are in the big pot (lots of nutes). Not a big problem at the moment and hopefully foliar spraying with very low ppm will enable the plant lower the concentrations of excesses (ppm) in itself. Granted, immobile nutrient excesses (nitrogen for instance) are difficult fix, apart from chopping the leaf with the excess. I choose to let the plant build up these excesses a lot on the older leaves, and then chop them off. Once I chop them, any additional excess will go into the next oldest leaves, etc etc. I'm finding that they don't use a lot of water, although I am foliar spraying so this will account for a bit of this. Bi and Tri where flushed 8 days ago and weighed 18.4kg and 17.4kg respectively. Today they are 15.4kg and 14.4kg respectively. That's not a lot of water use over 8 days imv. I think I must have been very close to root-rotting Bi & Tri. They still have ~ 10 days water in them, so 18 days in total (they'll be dry about 10.5-11.0kg) which I think is a long time between waterings. Photo's: M: 3: Bi: Tri: Happy Growing!

Tri went into darkness last night at 7pm after a 12hr day on day 60 since breaking soil. She'll be in darkness all day today. Bi will join her this evening at 7pm for her night. They will both be brought out at 7am tomorrow morning where they join the others for an hour of 135rw of LED 'sunrise' followed by 11hrs 660rw of HPS (3hrs of LED from noon-3pm also - 'highnoon') before being put back into darkness at 7pm while the others have another 5hrs of HPS and 1hr of 135rw of LED 'sunset'. Bi will have had three more days of flowering transition than Tri. Lets hope this darkness routine does hurry up flowering. Fingers crossed. Extractor fan only on during daytime. At night it's off to help up humidity, although the airflow fans are still going. Tri before going into darkness. Ruler is a 30cm from media for an idea of height/scale: 'High noon'. Largest fan blows across the HPS light. There is a piece of Perspex plastic taped under the light to act as a cool-tube (reduces leaf temp by 7c compared to not on). Fan far right is upside down to blow air under the pots/ circulate colder air. LED at a angle of about 65 degrees. Spray bottle in there to keep warm. Canes used for LSTing and placed in media before roots had time to grow to them (ie, just after transplanting, so as not to damage roots): Happy Growing!

Yup, they look like they have their little arms in the air waving & clapping away They look really healthy with lovely intermodal spacing imv.

A short video of the girls this morning. They have had a small defoliation of the bottom stems & leafs, and some side shoots form higher up side shoots. Tri will go into 30hrs of darkness tonight at midnight as she's really filled out of the last two days: Happy Growing!

A short video of the girls from a couple of days ago: Happy Growing!

I've selected Bi as the plant that is most likely to be ready to be harvested by competition end date. She's 32cm tall and growing quickly, with the side shoots coming out from hiding under some quite thick stem leaves. That's something I'm noticing about these WR, the shoots hide beneath the stem leaves for a looooooong time. She's in a 24hrs of darkness period (6 hours in) to hopefully help initiate flowering. Happy Growing!
