Heat Stress or Not?

600 watt Digital HPS, AC coming in to keep room a cool 74 degrees(in an apartment). DWC using Pure Blend Pro (Grow and Flower), just Flower in flower room. I've read about PBP and how it has to be cut down a lot. So I changed my water because it looked kinda high with the claw effect on my plants. Now there is some brownish - red looking striations on the leaves and there is only water in now no nutes. So what do you guys think? BTW love the new look on the site, thought I was at the wrong place!!! View attachment 925216View attachment 925217View attachment 925218View attachment 925219View attachment 925220

have you scrubbed your tub clean between change-outs? what is your ph? are you using flower nutes? if you're in a tub with plain water you'll see future problems too. at most, you should have decreased feed %, but not stopped all feed.
