I need to double check a couple of things with you:

When you got the clones were they already rooted or did you root them?
Plants are at least 3 weeks old?
You just transplanted into Fox Farms Ocean Forest not Ocean Breeze, correct?
At time of transplant you fed Fox Farms Grow Big at what rate? Is that the Fox Farms recommended rate?
Do you have the Fox Farms feeding charts? If not, you need them. FoxFarm Soil & Fertilizer Company

edit: And how much is a capful?
