I'm pretty sure Dyno-Grow is not organic, and the Botanicare Pure Blend Pro is (at least 99%). Liquid Karma has these ingredients:
INGREDIENTS: Dolomite, potassium carbonate, fish meal, sea weed extract, magnesium sulfate, humic acid (derived fro leonardite shale), water soluble vitamins.
Much of the Pure Blend Pro line already includes some/most of the nutrients i.e. fish meal, humic acid, etc. that are in L.K. There are differences in the grow vs. the bloom a bit, but essentially- Liquid Karma doesn't add any value IMO. Same thing with the Pure Blend Tea- another item that includes most of the same ingredients as the others.
If you are using their Pure Blend Pro line, just add their Cal/Mag- and nothing else should be necessary to grow exceptional plants. Unless you like pissing your money away.
