Hey everyone thanks for having me! I’m new to this network and looking to learn from the best. I’ve been involved with multiple 48 plant rdwc grows as a helper in the past and have recently set up a 2x4 tent of my own and feel lost. I don’t claim to be an experienced grower by any means, hence the multiple issues and questions I have this early in my grow. I am running top fed rwdc to 2, 5g pails and my res outside the tent. Transplanted my rock wool seedlings into the net pots 2 weeks ago feeding plain ro water for the first week then bumped up to 400 ppm with good results using 3 part flora series. Yesterday I did a res change as I noticed some minor algae buildup (likely from light leaks I have since fixed). Used ro water and brought pppms to 420. Since then the girls are not happy. Each showing different symptoms, leaves drooping/ bending, curling up, spots on leaves, yellowing, purple branches.. I don’t know where to start! My ph is always between 5-6, temps between 74-78, rh 50-60, 30 inches away from a spider farmer 2000 at 50%. And air stones in every bucket .Any advice would be greatly appreciated as this is the second set of plants I’ve tried to get going in this tent, I waisted 3 weeks germinating seeds from crop king for them all to be duds, I don’t want to start over again. If I’m over reacting that’s great just please tell me!
