I'm thinking the Veg 604A its a botanical blend of Kelp and plant extracts.
My other question is should I be using my Blue Labs truncheon, for measuring PPM, EC etc? I grow in soil mainly and not sure if I should be using it at all. Not sure what levels of stuff I should have anyway lol. I just measure out nutes by eye.
