LMAO!

I think the heat is affecting those plants, and agree with Weedhound that they're probably rootbound... which, in itself, can cause all sorts of other problems. I've grown outdoors before, but never in a greenhouse setting. In the southeast US, temperatures can get pretty warm. When it would get up into the 100s, I found myself having to water much more frequently. (My watering system was pretty basic - it included me, a couple of buckets, and a creek. :stoned If this is where your temperatures are hovering, you might need make adjustments to your watering system to compensate for the added evaporation.
