I have the dry CSM+B for my trace... how much would be equivalent to 15-20mls? How much would I add to 250ml of water to make a solution? 1.5 Tablespoons??? edit *** used the Nutri-Calc and it gave me 3 Tbsp per 500ml or 1.5 Tbsp per 250ml of water to equal 25ml 3X per week *** edit
Also, if I use Epson Salt until I get my MgSO4 from Greg, how much should I use to get 1/2 tsp of MgSO4? I wasn't sure if the concentration was the same with the ferts vs. the Epson Salt.
