Has anyone used Jacks GP 20 10 20 for daily feeding for indoor plants? Medium is 50% peat 50% vermiculite. This would be for the whole grow cycle.

Too heavy on the nitrogen for cannabis in my opinion. The 5/12/26 is a better balance for start to finish. A little boost in nitrogen is helpful during the transition stretch but 20/10/20 nitrogen portion is too high
