Spring 2023 Fastbuds testers

I noticed some leaf discolouration. Based on slow release amended Gaia Green, I am less inclined to say cal/mag issue. I think it was either P or K deficiency, which I corrected by providing a weak 2ml/gallon feeding of bloom over this week and a pulse of 4ml/per gallon on day 1 of this week. I noticed some yellowing of lower leaves on largest plant, suggesting soil amended N is decreasing and now the plant 2312 is stripping leaves. I intend to give a feed of 1ml of micro in weeks 8 and 9 to provide a little N as we finish this grow off. Flowers are developing nicely and I seem to be sufficiently managing heat and feeding to keep the plants happy. Lights were operating at 75% max output for week 7. Operating at 500 watts when all lights, fans, and exhaust running Start of week 8. 1ml bloom, .5ml micro, .5 ml floralicious plus, cane molasses and kelp. 2ml bloom and 1ml micro.
