I am having an issue with my plants. I am growing in ProMix HP with 25% added perlite and a 2 in perlite bottom. I am feeding GH flora series. I noticed nute burn and most likely lockout. I flushed and top dresses my medium with a little Bush Doctor Coco Loco for its organic amendments. Please help!
