What is causing the yellowing?
You look later in flower and the plant is eating it’s stored nitrogen. Hard to tell from the yellow light but looks normal for your stage.
Could also be nute burn. Have you checked your run off PPM?
Are you flushing?
can u post some pics in normal ‘white’ light.?
I haven’t but it’s because the soil I use doesn’t need much food. I do think it could be nute burn though because my ph meter wasn’t working right and I watered with 8.5+ water. Nute lock out. When I corrected the ph it took in what little nutes I did use. Its also ready for he est, so I guess couple of factors.
I am flushing now.
I will try to get some in white light. Thanks.
