Icahbod Crane uses Jack's 5-12-26 plus Calcium Nitrate in coco DTW... check his thread in the vert subforum... it's called "My Vscrog" or something like that... great thread.
Cara from veg to flower I use the 5-12-26 at 3 grams a gal ,cal nit at 2 grams a gal and epsom at 1 gram a gal. In the 3rd week of flower you can add .5 gram gal of 10-30-20 or 0-50-30. Thats what I am using in peat and soil. It working out great I like it better than veg+bloom so far. I am also adding silca (agsil-16h).
Cool. Thanks guys. The only issue I see with the 5-12-26 is the need for addtional powders to be added. The Classic seems to be more 1 part and thats what I want to give a SHOT.
