Man, I been shooting mine with Miracle Grow every other week n deep watering once a week plus hitting it every day for a few minutes with water. Right now I got plants just over 5 feet tall n loaded with Maters. I have about 15 or 20 on each plant. Just ain't big enough yet to fry up. LOL On the splitting, I heard something about the watering. To dry and to wet will do that. Course I heard about to much of some kinda nutrient to but ain't remember which one.
