Dolomite for sure otherwise you have no pH buffering or calcium/magnesium.. Coco is pretty calcium hungry as a substrate.
Looks like this thread may be the place to ask: What is the reason that Lime(or Dolomite) and Fertiliser should not be added together? In another thread Troutman says Lime first, Fertiliser later but does not explain. So ... Why shouldn't they be added together?
Wait so you're supposed to be mixing the base mix with lime first and then mixing again with the fertilizer? I've been just mixing it all at once. Had some ca/mg related deficiencies this last run that didn't make sense to me since I'm using all the right inputs posted here. I figured it was the strains I was running maybe just needed more. Was gonna up the lime 50% next run.
Am I supposed to wait a period of time after mixing the base to allow these ionic exhanges to happen? Any need to wet the base mix first before mixing in other amendments?
