Calcium Citrate Powder

Does anyone know if my plants would be able to make use of this form of calcium?

Thanks

I wouldnt use it. Its a very common food additive and its the stuff they make Tums antacids with. Just get some Cal/Mg if you really need calcium....What are you growing in? Soil. Dro. Outdoors?

Hey, here's some more info

Indoor
1/4 happyfrog soil, 3/4 promix HP soiless
Jacks Classic nutes(no cal/mag)
Epsom Salt for mag
edit: tap water too (maybe has calcium.. dont know)

And I had some of that calcium powder laying around, figured maybe it could fit the job

thanks
