1st "Organic grow"

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?

Gotcha. So I'm personally not a soil scientist so I can't tell you what combination of your amendments will create a balanced soil, but you do have blends there with the Dr. Earth. You have one for Veg and one for Flower. That may be all you need. Maybe someone who uses Dr. Earth can chime in and let us know what dosage they give to their plants and also if that provides enough calcium like you asked.
