Well the problem is you are growing in Coco which is a hydroponic substrate and feeding organic SOIL fertilizer. This does not work well.

Agree with MOG, just to be specific I'd guess that leaf damage is a result of P lockout. Mr. Canuck, who it seems you're trying to mimic, uses a HUGE amount of work castings to buffer the soil and allow the plants to consume all that dry slow release fertilizer. Did you include any in your mix?
