Today is day 70 since the plants have sprouted, and day 27 of 12/12 light schedule.
The buds have gotten a little plumper this week, particularly on the Train Wreck, but that plant seems to be a few days ahead in the flower process. I've been trying to overcome the yellow leaves on the Train Wreck plant, and I keep feeding the plant according to the "aggressive" feed chart from General Hydroponics, but it just isn't enough. I was a little worried about the pH in the soil getting too low or something, but the meter I have says it's actually on the high side.
This point represents about halfway through the flower stage since I plan on going about 5 more weeks. The Train Wreck is expected to flower for 9-10 weeks, and the Royal Runtz for 8-9 weeks. The purple color on the Royal Runtz seems to be growing on each of the buds, and has a clear correlation to the amount of light hitting the bud. I'm interested to see if the buds below the canopy get the same purple coloration as the top buds.
Temperatures were getting a little high early this week when I turned the light up to 95%, getting to about 82F. I moved the power supply for my light outside of the tent hoping it would reduce temperatures, but it only brought the temperatures down to 80F. On the bright side, my controller is generally keeping the humidity at 60% or less, compared to when the temperatures were at 82F and the humidity was closer to 65% most of the time.
I measured the PAR for the tallest bud in the tent, which is getting about ~1200PAR, compared to the ~650PAR the Royal Runtz is getting. I wish I could lift up the Royal Runtz more to get it closer to even with the Train Wreck, but I've already lifted it up and both plants are bound by the scrog net.
I noticed powdery mildew on a few leaves on the Royal Runtz, which I've been worried about given how bushy it is. The fan in the tent also doesn't blow directly on the plant, so I added a fan from my other tent to blow directly through the plant from the bottom, and moved the original fan to blow more directly on the Royal Runtz. I'll be turning off the humidifier completely for a bit while keeping a close eye on the plant to see if any more PM develops.
Edit:
While looking closer at what I thought was white powdery mildew, I noticed there were pollen sacks dropping pollen on the Royal Runtz plant. I sprayed the areas I saw polled/sacks with water and removed any buds I thought may have been affected as well as anywhere I saw pollen sacks. I'm sure I missed plenty, but I'll be watching the plants extra close from now on and assassinating any potential sacks I see. We'll see how seedy the tent gets, I guess.
