10/14-10/20
10/14: After lowering the temperature in the tent about 5 degrees, the leaf tip burn has stopped. This is the second time I believe I have successfully controlled the Grow Dots release rate with temperature adjustments (maybe--more experiments are needed, but it sure seems like it gives you a great amount of flexibility).
The tent is crowded, but the temp/RH/VPD have been perfect (see image).
Branches seem too spindly. I'm worried that the buds aren't going to fatten up enough. We'll see. Lots of time left.
Still hand watering (1/2gal per day per plant)
10/16: The lower fan leaves on one plant are yellowing a lot (the left side, or "bigger" plant with the larger light). They also happen to be below the largest buds. The largest buds also happen to be closest to the light. After reading around a bit, here's what I think happened: The parts of the plant closest to the light were getting too much light, which caused the fan leaves to yellow and start to die. The DLI was close to 60 for those parts of the plant, which is WAY too high. I turned it down, and now it's around 45 for the big buds, and 35-40 for the remainder of the plant. I wish there was a way to move the larger buds further away from the light, but there's not because of space limitations. I still have some concern about the size of the buds. I think I'm going to end up with a whole bunch of apricot-sized buds and no big kahunas. It doesn't seem like it will be the yield I hoped for, and I am no sure why. A common comment in the Glookies diaries I've seen is that the yield was below expectation. Lots of time left--maybe they'll fatten up a lot.
10/16 (again): I had a little extra time today so I built a DIY CO2 generator. See video. There's some chance it will overflow and/or explode and spray yeast and sugar all over the place. I plan to watch carefully. The pump and heat mat are on a timer so that they're only going when the lights are on.
10/20: Last day of this week. I turned down the light and the leaves stopped yellowing. So, problem solved. The plants look as good as any other Glookies diary I see on here for this far along. I am using every available inch of this tent. I've been as careful as I can about keeping things spaced for airflow. Daytime temps: 78F; nighttime: 67F. Humidity staying steady at 55. I didn't water yesterday because the bags felt too wet on the bottom. The pot bases are bone dry today, so I should be good to water again tomorrow. I hit them with Recharge day before yesterday.
