I agree it's just a rock solid product. I haven't tried the Tri-Flex though. All the other ferts and supps work awesome.

JB is also right that it's a good idea to start with a basic understanding of the plant so you can effectively gauge its response to the general schedule- there are so many variables. Watch your pH and calcium availability, then watch for deficiencies and burn. Learn to spot them early and know what to adjust, and how.
