Have you looked at the "Dealing with heat" thread? (in my signature)

If you restrict light, you risk internode stretching.

Are those pots draining under your shed? If so, do you have a moisture barrier or other mold protection?
Rusty Trichome Reviewed by Rusty Trichome on . Soil PH too Low Hello first post on this site. I am a newbie outdoor grower (green house actually). The PH of my water is around 7.2. My soil PH is around 5.5. My soil consists of CA Supersoil, Vermiculite, and Perlite. I use Jack's Classic 20-20-20 every third watering. Some of the big fan leaves are starting to droop a little and are slightly discolored. I'm sure this is the PH issue. I have read about adding hydrated lime but to raise it but that it can also be toxic and bipolar for PH testing. Rating: 5
