HELP Can I USE ZINC TABLES for adding zinc???

Well im broke as a joke and I need a source other than an expensive zinc fert to solve my issue. Im doing hydro.... can i dissolve zinc tab and administer?

I wouldn't, but that's just me. You have no idea what the material in that dose will lead to in your grow medium, not to mention the stuff you don't know about, like binders and fillers, etc.

..... If your really broke, go cash in some bottles and go buy the smallest package of Miracle Grow and use it at 1/4 strength.
