Your well water must be good but you still need cal-mag plus.

If you would like since you have soil too and this is your first hydro. Do a test and show how it goes. First back off on the miricle grow mix a little. Get your PH down to give or take 6.0. Just a teaspon of ebson salt in each bucket for mag part of cal- mag can get you by. Then just keep us up on it.

You really need the hydro nutrients and the cal-mag unless your like my bro latewood and know all the parts to make it for pennies. General Hydroponics is one of the most used because the formula is made for MJ. I ran lucas you only need 2 of 3 parts so cost is down.

Do a search on loc nar. I did a thing where I cut massive roots back just to water level and the plant hardly slowed down.
