Cal/Mag deficiency with one of them visible in the bottom left of the image. I've given a little cal mag. The runoff is 1000pm with 800 input so may be due to some sort of lock out.
Thursday 😟
I committed to a pretty big defoliation job on them. Nervous about it as I should have done it just before switching to flowering cycle. But there hasn't been too much stretch or pistils and I know some people do a defoliation at end of week 3 of stretch so here's hoping it directs energy to the right places!
