Both the Gravity and PurpleMaxx aka SnowStorm aka Stacker are seaweed-derived non-nutrient supplements that I think are meant to deliver certain hormones found in kelp.

I give base nutes in the water, micronutes as foliar if needed, and the humboldt shit always by foliar. I'm a little scared after also losing a crop! lol
