Well I am using a combination of Jack's for my grow I just started as an experiment.
( Palm, Acid, and Bloom ) not a bad price at all. I'll keep a record of what happens in My journal.
I plan on adjusting the ratio's based on a few NPK charts I have found for different stages.
Acid Special
Total Nitrogen (N)......................17%
10.58% Ammoniacal Nitrogen
6.42% Urea Nitrogen
Available Phosphate (P2O5) .........6%

Sulfur (S) ....................................14% 14.0% Combined Sulphur (S)
Boron (B).................................0.02%
Copper (Cu)............................0.05% 0.05% Chelated Copper (Cu)
