1st grow - Auto Rippers

Update 5th week - Trouble in Paradise I had hoped that I would get through the grow without fertilizing, as this Terra Preta soil is supposedly able to do that. Unfortunately, however, both plants have been showing signs of trouble in the last few days. Both have these beige, light brown spots on the leaves. It could be a lack of nitrogen or calcium or the pH value could be too high. I hadn't looked into this yet, but the pH of my tap water is also quite high at 7.7. So both are getting some Bio Bizz Grow and a little CalMag now, the Sour Ripper is also getting some alga bloom Before each watering, i also lower th PH to approx. 6.5 from now on. Yesterday they both got a summer haircut: Off with a few broken leaves and some fan leaves that are covering the flowers. They liked that, as it looks a day later. Regarding LST i slightly adjust some branches here and there and tuck some leaves. I also still try to get my lights in the right distance. Could that also be an issue here?
