this is my first time doing dwc in 5 gallon with air stones. I got my nutrients all ready to go. But how much cal mag by emerald harvest 2-0-0. N-P-K
Should i add. First week of seedling i gave 5ml to one gallon. Seems to do fine. Or should i add it to couple more gallons as well.

what ever the directions are cut it in half for all nuts you use and how much call mag depends on the water as in city, water well hard or soft? water RO water i use well water but have good well water not to hard and come out of the tap a 195 PPM so i really dont use cal mag unless i see signs of it being needed this is for my home grows

Then learn to pay attention to the EC instead of counting on exact teaspoons or whatever. That’s the point in recommending it. But I have a feeling you already know far more than me.
