Hello, I noticed this yellowing with spots that look rust color. The plant overall looks healthy but this seems to be slowly creeping. I'm in Coco hempy's 77 temp T5 light for veg Aqua flake AB plus flourolicious. 5.9 -5.7 ph and 5.5 run off. I feed two times a day with about 40 % run off. Wondering is this a cal mag issue? Thanks

Your run off is low enough to get cal mag lockouts. I'd raise your pH so your run off is at least 5.8. Maybe try mixing the nutes to 6.2.

Thanks for the reply, I've adjusted to 6.2 ph and my run off was still 6.2. res must have gotten dry over night. I'll update in a few days.
