@Ryan Golightly This is a spreadsheet I have used for drip to waste in rock wool. The greyed out PPM is not calculated; it was the recommended number from GreenLeaf at that time. The formula has changed twice since I used this. This is going to get you close no matter which MC you have. Plug in the gallons and % strength and it tells you how many grams of what to add.
Remember this is just one tool, Watch your plants and listen to them.
Edit PS. this is Mega Crop 1.0 so if you are runnung newer versions use less extra Cal-Mag - maybe none.
