About 3 weeks into my first DWC grow. I started noticing these tiny little brown spots on the lower leaves which has now spread to the rest of the leaves except the newly grown ones. I check my pH every day twice a day. Usually stays between 5.5-6.2. Temp inside the tent (tent is 2x2) averages at 77 F. Been using frozen water bottles to keep my reservoir cool. Temp in the reservoir averages 68-74 F. I use General Hydroponics Grow(1 tsp), GH Bloom(1 tsp) and Hydroguard(1/2 tsp) to prevent root rot. I have a fan sucking air out to keep the air circulating. Also have a fan directed towards the plant it’s self running on low. Been doing all kinds of research, but I can’t narrow it down to one thing. Calcium, magnesium, pH issues, or root rot are the only pictures I’ve seen that resemble anything close to what mine look like. Any kind of help or opinions would be greatly appreciated.
