Hey fam
Starting a tent with organic ferts. "Dr. Earths" to be specific. Its was cheap!
My questions:
1. Is PH'ing water a best practice? and if so 6.5?
2. What do I do for calcium? (Epsom salt for Mag?)
3. I have tons of fish tanks... does anyone have experience using the "mulm" from filters and or aquarium by-products in their grow?
I am using RO water (btw ph's rather easily compared to vegas tap)
