    Heat has been an issue until yesterday. I installed a portable ac as a temporary solution. Temps remain in the 75 range during lights on. I just increased the light distance from the tops of plants. 1000w hps. Does this look like it could be heat stress related? Cal-mag problems? Using tap water (170ppm@.05) with maxibloom only.

    I was told this looks to be heat stress. Backed off nutes to 1 ec and ph to 5.8. I have raised my 1000w mh to 20 inches above canopy and the temp remains @ 74-78 lights on.
