I think that as long as your using a good soil mix.... either store bought or your own you should be fine. If your mixing your own soil I also like Dr Earth amendments. I would also invest in some greensand.... It contains many of the minerals I think your looking for. If your looking for a store bought mix I would suggest Root Soil by Aurora. Has the greensand and mychs. Hope all this helps and everything goes well. Peace and Bud.
