Hello! I am having a problem with leaf curl on two of my plants. The temperature is 77 degrees at their top, RH is 55% and there is a steady breeze blowing through the tops and above them. They are under a 400W Metal Halide bulb which is 15" above them. Take a look at this pic.. am I correct in thinking this is heat stress? I didnt think 77 would be in that bad! ~Experimentalist
A second opinion never hurts, But as I put up on your main thread, Heat Stress all the way. Did you check your humidity level, that in itself will cause the leafs to curl up of on the 10% low level. Add the 77 in the equation, and there you go.......
I'm with you, although I do like to do things on the level from time to time. Nice to see another brother out here.. I've met like 15 or so of us so far! ~Experimentalist
