Need help with the leaf problem. It was only 1or2 little orange/brown dots couple days ago. I check the PH it was too high(7.0) I dropped it down to around 6.0 and the problem seems getting worse? Im running a 75-80 temp, 2x24w T5 6500k. Is it Mg/Ca def? or light burn? cause I had it pretty close to the plant maybe 5 inches. Please help!!
