I've had this issue in the past using completely different grow methods and grow environment. I always chalked it up to heat and light burn (was using 600w hps within a foot of the buds). Now I'm using Mars hydro ts1000 18 inches from the top. Temps are 70-85F. Humidity now is 30-40. Temps used to be 65-75 with humidity 60-70% prior to dehumidifier 2 weeks ago. These plants started outdoors and I brought in due to powdery mildew. I was thinking all the spots were phototoxicity due to the foliar sprays but it's gotten worse and I haven't sprayed in a week or so. Theyre in FF cocoloco with natures living organic supersoil concentrate. Top fed 3 and 7 weeks ago with a cup of dr earths flower girl (think I was supposed to use half that). Was thinking its a mag deficiency so added .25 tsp of calmag+ and .25 tsps of FF chaching since I had it laying around. After chaching a huge burst of new pistils emerged and the leaves yellowing/dying ramped up. Otherwise I water when dry (every 4 days) with half a gallon of tap water left out for a few days. Tested at 6.7 ph and 40ppm. I have another plant I've been treating the exact same way except a bit farther from the light and she mostly looks fine. I'm totally stumped with this long term issue I've been having. Clearly seems to be a me thing. Please help me grow as a grower!
