Hey thanks a lot everyone! I just set it to Red spectrum and 12 hours off 12 hours on, both in the same day, three days ago. It’s a fairly new switch. I do have the veg option still but I figured I should turn that off to stop encouraging it to veg because it’s a pretty tall auto flower and I’ve used low stress training a lot as you can see. I did measure the PPM and pH of the runoff which I haven’t been doing at all until I had issues and realized my pH dropped to a 5.4 runoff and the PPM was 1100!! Danger levels, I was really shocked since I never go over 250 ppm with watering per 2.5 Liters, the plant being in a 7 gallon black pot with drain tray. Using Foxfarm soil. The nutrients must’ve packed into the soil to densely and as far as Ph goes, I usually pH my tapwater with pH Down before adding it to the soil so the roots could absorb better but I guess it had made it overly acidic overtime. So lately I’ve been flushing it with regular pH from the tap which is 7.5, sometimes 8 in fluctuation. seems to have made the leaf tips stop burning and perk up a little. Maybe a good sign?
