Take 2 6 inch pots. Use vansil in 1 and solution grade gypsum in the other. Let us know which shows up in the sap first. Or water some ksil in with your gyp and see what happens
I can do that. I have some in 6" that I can do a lil report.
My main concern with watering in B is going to far cuz 1 ppm at a time using solubor in 2 gallons might be tough.
I sprayed some pht Ca/sea stim/accelerate/pacificgro on the ghouse. I have a history on paper as what they where testing. So we will see. The K:Ca has been running 2.46:1 on top. I suspect it'll be closer to 1.5:1 but I don't want to run all the K out to much because they're in flower. I'm a few days away from putting a lil ksil/K sulfate on for top dress.
