Heyyy, while you guys aren't busy...I have a question.
My lights are out now. But I can describe pretty well, i'm getting some inward canoeing, and inward tip curling (the dreaded weed claw). My understanding of the condition, is that it's 1 or all of 3 possibilities.
1) Heat Stress (VERY POSSIBLE, i've been battling heat since the season changed so much. (it's supposed to be just under 100*°F Tomorrow!!!)
2) Low Humidity (Also very possible, the heat in my area is very dry. My grow room is at a pretty constant 20% rh)
3) Excess N during the transition to flowering cycle. (I know some plants are sensitive to N when going into flower, and just when I switched to flower, I gave them a dose of 1/2 Veg, 1/2 Bloom Nutes in order to transition them, however I believe that the N between the nutes was to high for the beginning of flower. The grower I got the clones from to begin with recently warned me about excessive N during flower.
Now i've taken steps to correct each problem.
I added a "ghetto" ac unit, it's a tote filled with water and ice packs (frozen bottles of tap water) with my stanly blowerfan (which i'm still in the process of modding) blowing down into it. This handles the heat mostly, and the water and fan brings the humidity up. I've got it around 40% or so now. And I watered today with my bloom nutes (1-5-4) @ half strength, just to infuse a little Phosphorus into the mix so they can get flowering. And also watered with an extra gallon of pure water (between the 5 of them)
They each got about 20oz or so more water then usual. And when they typically get about 45 each, and they each received 75oz each this watering. Only 30 oz or so each with nutes.
Here's my ferts.

EDIT: Here, i've found a picture of something close to what's happening, it isn't nearly this bad yet, but I work on problems early and often. Some of my lower budsites are doing this too, along with a couple of the tops of the plants. I noticed it a day or 2 ago, and kept an eye on it, but i've noticed it worsening and have decided to be proactive..
This is just some pic I found that demonstrated the type of curling i'm talking about. They aren't that curled over or in yet. But in order to keep them from looking like this, i've taken my procautions, and am discussing it with the group!
Thanks guys!
