Hello my Freinds, I am in week 5 of flowering 4 master kush clones, and am having a problem. reading through plant problems here, i'm thinking a calcium issue? I water with tap water that has sit 48 hours, and ph to 6.5 - 6.6. i have not added any cal/mag. growing in soil and using foxfarm trio for nutes. tent is a 54" x 28" x 80" with two california lightworks solar extreme 250 LED lights. I have read that with LED light you need to add calcium in coco, but not necessaily in soil with top water. Any thoughts?
