I grow cannabis in DWC and this is my personal experience. I don't recommend tap water as cannabis plants suck up everything and there can be some nasty stuff in your water even if it passes Government tests. If you must use tap water you probably won't need calmag, but if you do simply add 2-5ml of your micronutrients between water changes (assuming you're using GH Trio). Use the same idea for other brands. If you're using RO WITHOUT remineralization then you're going to defiantly need to pick up some calmag and use it as directed.
very helpful, subbed
I made WSC Water Soluble Calcium from egg shells and Vinegar from a KNF Recipe and added a bit of biter salt so I made my own Cal-Mag. =)
Love this idea 💡
Lol defishenshe 😂 idk why that made me laugh so much.
lol 😂 I was like “what do I even do with this?!” In production lol
Ur rain water has next to no mineral content it’s all from the nutrients
You are correct, very low EC indeed
Are you someone who needs to pick up Cal-Mag or are you someone who already has it and just realized that you won't need Cal-Mag?
