Hi. I’m a beginner grower with 3 indoor auto plants (they’re outside just for the photo shoot) 1 euphoria and 2 night queens. Almost 7 weeks old and around 40-50cm height the bigger ones, the smaller one had a heat stress in the early days and I over fed them with nutrients I think. Just started to measure my water ph which is 8.5 and using phosphoric acid to bring down ph. I can’t figure out what’s wrong with them leaves turning yellow from the top of the leaves but veins are yellow and in between greenish. Also there are bronze/purple leaves too. Is it the end of their life cycle or something seriously wrong with them? Thanks

With viparspectra 95w led and 200w meizhi led( but this one aren’t 200w for sure might be 100w). Feeding them with biobozz bio grow and bio bloom as per their nutrition schedule so I might over fed them.

well by the looks of it, they seem to need a bit more nitrogen, it doesn’t look like your over feeding too much.
i’d say some heat or light stress, but those lights i have no ideas about or have i grown autos, it could be a naturally fade with slight ph issues.
wait for a reply from someone who can help out.
