I don't understand what I'm doing wrong.. checked the PH and its at 5.1, humidifier, RO, H202, Sensi grow part A + B, PH down natural, epsom salt, pump, aerator. PPM is 339 @ 76 F. The leaves are drooping down and theres yellow spots on the leaves. http://forum.grasscity.com/indoor-m...elp-dont-know-what-problem-pics-included.html
