Oy vey... that's a lot more than "10% soil" mixed in with coco. 50/50 coco and
promix plus a ton of organic amendments.. plus top dressed fertilizer on top of that? And molasses?
That sounds like a recipe for disaster. No wonder you're having issues.
A bit of advice if you choose to take it, next round use either pure coco, or pure
promix and dont add anything to it. Then use a complete and balanced base nutrient. A good one, something like pure blend pro, foliage pro, hell even gh 3 part or floranova. That is all you need man. And more importantly all the nutrients will be in the right proportions and the media will perform as it's designed to. You've gone overboard trying to give your plants too much love. It happens. But the mantra "less is better" is extremely accurate with regard to growing weed. For real.
