Still scrogging, but I'm noting nutrient burn on new leaves. I learned that I needed to adjust my nutrient mix to 1/4 or 1/8 of recommended. Because of gravity fed drip irrigation feeding multiple times in a week. Something 3-4 feedings in one day. 700ppm x 12=crazy burn. However, using Foop nutrients it's hard to burn because of slow release. Just a build up in medium coco coir. Second flushing of the coco coir.
