yan420answered grow question 9d ago Hey growmie, my experience with Advanced Nutrients is limited, but from what I know the Foliar Four Pack is actually designed for foliar spraying, AN markets it that way.
Just be aware that AN products are very expensive for what they offer.
If you want to do foliar feeding, there are cheaper things that work just as well:
kelp / seaweed extract
aloe vera
Formulex
All of these do the job without spending AN money.
Personally Iβm not a big fan of AN because of the cut-throat prices, and most foliar feeding isnβt even necessary, keeping the leafs clean helps a lot more.
