I just bought this fertlizer for my soon to come citrus trees and my current lime seedlings. Seems to have the right #'s... but I want to be sure before I use it.

6-3-3 for the ratio and p2o5, k2o, calcium, sulpher, and then 25% organic matter

Will this work? anything else I'd nee to supplement with?

it says it is slow releasing w/ some fast acting as well.

buy epsom salt, it would be a good supplement source for Mg.

thank you for responding
