you dont use it as a foliar feed. use it with your normal nutes
You can foliar it just fine. I've been using it and it does have some pretty noticeable results. It is a lighter ppm blend than the original Snowstorm and Purplemaxx, so foliaring doesn't burn the plants like it use to. I used as foliar for the first 3-4 weeks, then switched to just adding with the water.
The biggest difference is how much resin develops on the parts you end up cutting away anyways during trim. If you make hash, this stuff is liquid gold, if not, you might get some pretty pictures but it won't affect the smokable buds that much.
