I think I have a nutrient issues but well.. Just to be sure.. First grow ever. RDWC - now in 2nd week veg. Following the Cultured solutions nutrients @500 charts. Now @ 120ppm. Doing a water change tomorrow. I have some orange/brown spots on a leave and on barely all the plants, some spots are dark grey... Another one (the one in the middle) is curled up... Day: Temperature is 76-78F. Humidity 50-55% Water temp is 69. PH @ 6.4. Night: Temp is 71-72. Temp humidity is 50% Water/Ph, same. Strain is Critical Mass. I'm kinda confused Plants are tilt up though, they are growing like crazy for the last 2-3 days. Roots are white, no weird smell Thank you very much for support!
