I use a 6 inch in a 4×4 and it totally does the job for a year now.

Well, 64ppm out of the tap is actually crazy clean and low in practically everything. It’s going to take very little pH down to get you to 6.5 ot whatever you run at, like just a few drops per gallon. Consider yourself very lucky and don’t worry about anytime water wise!

This is the way.

You’ll get all these little things that will frustrate you but, in my opinion, 1st year grower I took my chances with under feeding than over feeding. You can always add more but you can’t take it away if it is too much. Just a little tip. Don’t let it deture you bro. A couple months in you’ll be like hell yeah I got this now.
