Damn, I'm sorry this happened to you bud! I did a soil grow last year and couldn't get them repotted into their final big pots, instead I tried to manage with topdressing in 3 gal pots and they started going down hill fast! It was like a slow motion car wreck over a period of days. What I did is start feeding 1 EC of maxibloom, to LOTS of runoff...but only when the pot got light. So, sort of like how you grow with mineral salts in promix. I didn't multi-feed like with coco, I think I was feeding once per day or every other day. Always to a ton of runoff because I wanted to keep washing out all the stuff I had added through topdressing. Amazingly enough, it worked, the leaf damage stopped and the plants made it to finish looking pretty decent. I'm sorry to hear about your family issues, best of luck in working things out!
