Don't worry about the greensand, it doesn't bring alot to the mix anyway. Make sure you have the kelp though..... I'm not really sure how you could add this ta yer plants you have goin already. I reackon you could top dress em with it and feed em with a worm cast tea. That may buffer em enough for them ta grow??? or you could try transplanting. Carefully crumbling or rinsing ( with water ) away the soil around the roots. It's risky if you have never done it before though. Sorry I couldn't be more help. Good luck! BC
Thanks again B.C., as soon as I get my nutes I'll try crafting up some batches of tea for one night, and then getting them ready for a transplant after a few days.
Do you have any more input for knocking the soil away from the roots, or things to make sure that I don't do?
