Plants looking pretty good at the end of week 6 of flower. Colas are stacked and putting on weight.
At the beginning of the week I top dressed with 4 tbs/gal of worm castings and 1 tbs/gal of 2-8-4 Bloom. Watered it in at a PH of 6.2.
Mid week I brewed a PK heavy compost tea made from worm castings (4 cups), 2-8-4 bloom (6 tbs), micronized dolomite lime (4 tbs), epsom salts (2 tbs), and blackstrap molasses (1 tbs). I brewed for 12 hours before adding the molasses for the last 12 hours. It was super frothy and came out to 1000 ppm. I have been giving the plants plain de-clorinated water PH'd down with a bit of citric acid ever since and the plan is to continue plain water the rest of the way.
Pheno #1 is substantially more impressive than the other 3 plants, at least aesthetically. Will have to wait to see how it finishes and what the effects are like, but its the clear front runner for this pheno hunt. I have a few cuts that I took before the flip to flower, but I'm really hoping to find a few seeds in its flowers at the end of this run.
My Co2 tank ran dry today but since I'm growing in my furnace room in the basement, the Co2 level is steady in the mid 700's. I decided not to supplement the rest of the run and I've set my trolmaster controller to dim the light if the temp climbs above 77 F (25 C). Even at 100% the PPFD readings are only in the mid 800's at the canopy 24" from the light. Will keep an eye out for any signs of stress, but with mid 750 ppm of CO2 I think I'll be gucci!
Stress at the top of the canopy. Is this heat stress, light burn, or a combo? Something else?
Temp in the tent hit 92.5 F at one point, but it's been high 80's in the tent and the leaf surface temp's have been low 80's.
Light was 14 inches at one point but now 24 inches
Looking at your diary your growing in coco and been using very little nutrients. Also your ph is always at 6.5 which is at the high end for coco. If you get your ph closer to 6 and feed some blooming nutrients and cal mag she should bounce back. Try feeding a Ec of 1.2 or 1.4 and make sure you get run off. Go feed, let top inch dry, water, let top inch dry and repeat.
Hey Buddy by the looks of those leaves you might have a deficiency or pest problem going on. Do you know what's been causing it or have you been spraying anything on them. Just trying to help out, Peace & Happy Growing 👍
@QueenOG, spider mites and/or thrips. Must’ve been some larvae in the compost I used in my medium. Have introduced some pest control measures. Hope to keep them in check.
