Help me with grow. Income ppm 550, outcome 600+. Thought that was root rot, i make mix with water and Trichoderma, but nothing change. Ph 6.0. this photos from 1, 2 and 3 may
Try raising your light slightly, 20cm is very close, don't need too much feed at this stage and try running an 18 or 20 light schedule, some plants just really don't like 24 hours if this doesn't help it could be just be the genetics. 🌱👍
That is a lot of nutes for an auto at this stage. If the ph going in is 6.0 the outgoing could be some higher. Have you checked the runoff water for ph? I also agree with FG about light and time. Cheers
