I had some used coco that I had put in landscape fabric in a big tote with holes drilled in the bottom, left it outside and just let it rain through it to flush it out, it's been outside a long time. I just put some new sprouts in some in dixie cups and watered em in with a light clonex ph'd solution, and by the time I noticed something was wrong I only saved 2 out of 11. Ive only grew in coco a handful of times with good results but never started with fresh seedlings( straight from paper towel) anybody know what was wrong? Would they have a cal/mag issue that young?
