oyster shell powder is awesome.I use it. I make my own oyster shell powder and seaweed extract.good shit for sure.That's a nice simple mix . some one recently told me to try oyster shell flour instead of dolomite lime for cal.don't know how much better it is as iv not used it yet but the guy defo knows his stuff . however your plants look as healthy as they could be so there wouldn't be much point in switching.
