Day 24 Veg - Well, after some ups and downs, I think things are on the upswing again. After my last round of curling leaves over Thanksgiving, I've determined the plants got heat stressed. I normally leave the doors to the box cracked with an extra fan blowing and try to keep the temps around 75, but for 3 days over Thanksgiving, the doors were closed and the temps were in the mid 80s, even as high as 86, and with reduced circulation.
After a res. change and several days of running things cool and well ventilated, they're looking a lot better. I pruned quite a few of the older, larger, curled fan leaves that were under the canopy and were not getting light, as well as trained the tops throughout the SCROG. The new growth looks pretty good and most of the tops are above the screen, even after several training sessions.
Now to my question: SHOULD I START 12/12 NOW? Or give them a couple more days for the tops to fully clear the screen?
How much addtional height can I expect if I change to to 12/12 now?
How bout that trunk for a 3.5 week old plant??
