Advanced Nutrients Sensi Grow Part A+B WSP Professional Series 25lbs Set

Start with 1/3 dose and make your way up as they get big. Once huge then you could be feeding full dose (take into consideration other supplements and fertilizers and don't over do it). Dry fertilizer is the way to go. You stretch your dollar the longest and the dosage is tiny compared to liquid nutrients. Just buy yourself a seal tight container to store for pretty much until you run out there is no expiration.

Frosty AF👍This stuff is great for plants
