I worried about my "general" LED light. So i put lamps closer to the plants and probably burned them a bit. So pushed back my lamps and changed light schedule (18/6 instead of 20/4).
UPD:
On day 13 there seems to occur a problem with nutrition. Leaves are still yellow and start wilting.
This week this was memorable with the following:
1) Temperature
Despite I have had a fan running air in the tent and lamps raised up to 35 cm it was too hot for my beauties. So I set up a duct fan, which has dropped the temperature a lot (from 27 to 23). Although the duct fan should be sufficient I have also increased the distance from the flowers to lamps up to 45 cm (probably will return back).
2) Fertilizers
By the end of the 1 week I found some tips of leaves drying out and getting yellow. It turned out to be a chemical burn due to an excess fertilizers which I took for the nitrogen and magnesium deficiency. Fortunately, a solution was found before the plants were seriously damaged: I flashed the coir every day with clean water. I hope all that will be limited only by the loss of a few leaves, which seem to keep wilting and drying out.
One more thing. As I have decided to flash flowers with water only, I took a decision to invest to PH meter. It helped to reveal that my Advanced Nutrients "PH PERFECT" are not quite "perfect" not to say mediocre in terms of adjusting the ph level of water. My tap water is about 7,9 PH and 2 ml of nuts (per liter) change it to the best of 6,9.
3) Smell
This is the point I like the most. Little smell started recently. But it's nothing if smelling it from afar. But if you get down on your knees you will discover that Bruce Banner is strong sharp and fresh weed. But, the CBD Crack smells really remarkable. It's very sweet like throat syrup for children but fresh at the same time. And smell shimmers with mint and bubble gum.
This week my beauties feel better. I have finally figured out how to fertilize them without hurting: the first day watering with half of nutrients the second flush with PH-adjusted water. Spray them with magnesium sulfate solution (1 gram per litter) from time to time.
Also I applied LST this week. It seems to me that I have done something wrong because they look too bushy. I probably have 2 weeks more two correct it.
Alternating fertilizer and flushing with water one day after another work good. No wither, no burns. Healthy green color.
Probably the last week before flowering. Do you think I should already add warm light?
Fertilizers and water alteration still looks as a good solution.
It seems to me now that applying LST was a mistake because there is really not enough space in the tent and Bruce Banner has not even started flowering.
