My plants were deppish green ,I have 8 strains and they're all 9 week (on seed lab pack) .theyre ok but a fair bit behind and some look similar to the OP's pics above .Last night I gave them just pure water .Then as I wanted to start to flush I used fox farm sledge hammer .I let that dry then gave iguana bloom ,cal mag and a mills pk booster ,before I gave the nute feed I gave them a foliar spray with Epsom salts ,just gone in the room some of the leaves have died I have started to spray clean water on all the ones I treated with the Epsom salts .Is there anything I can give to help restore them as they were strong ? Also there @ week 7 .
Thanks
