Too much molasses and you'll get black/ brown spots on your leaves, and they will turn purple on the edges... I tried adding that organic soy drink stuff from the store 1x and won't even think about it again, too much vitamins I guess. I use molasses SPARINGLY and don't trust it , because it's easy to over-apply. I use organic cane probably too much, added with fish, kelp. I've read to avoid adding magnesium late in flower, because it'll burn/ taste bad. I don't know shit from reading, I learned from making mistakes.
