First grow, several strains, Sfg5000, SF supplemental lighting, Gaia Green, Foop, worm castings, and indacanja (never remember name)/Coco loco bush doctor.... I'm deep into my first grow, weeks from my first harvest (excited but a rough outing), but this topic is a different one. My Amnesia Jelly auto from sensi had an incredible start considering it's predecessors and has been healthy the whole grow. I switched from synthetic fertilizer to Gaia Green, Foop, and worm castings and my plants started to vastly improve. This one however looked ghostly, without color almost. I increased the dosage and the plant started to Green up but the center of the buds started yellowing. Is it from a lack of nitrogen or too much nitrogen? I'm assuming it's nitrogen.
