....Sulfate -> MgSO4. Its epsom salt and yes its a great supplement, i find more strains than none craving the extra mg kick late bloom. If needed ill add in 100 ppm and observe and take it up if needed.

Things are looking good around day 41 or so now. I did a complete res change at 750 ppm 5.9. Will begin flush in about 10 days.
