Question regarding FP and dolomite,gypsum etc...
This question is primarily aimed at tapla ;) but any insight would be nice. Also, I apologize if it has been covered previously.
When growing in 5-1-1 or gritty mix, are the calcium and Mg supplements such as, dolomite and or gypsum/Epsom, required in the mix if you are using a micro complete fertilizer such as FP?
Are any fruit or vegetable plants known to be accumulators of metals such as Mg or selenium?
If so, which way would be safer for growing edibles; FP (or similar) and no supplements in the mix, or supplements in the mix with Miracle grow or similar lacking ca and mg for fert?
