PH was 8.4 according to the freshwater fish take test strips I got.

This is water that I have had sit out for 2-3 days roughly and I use old (rinsed out) 2 Liter pop bottles to let it sit in.

I assume 8.4 is a bit of a problem. How much of what should I add to it to make it the right range?

I didnt test drain water since I figure this will be an issue.

First time, having problems Here is my situation: Closet setup, am using a HID florescent ballast for the growth phase then will switch to a HPS bulb for flowering. I have been running the florescent setup 24/7 for a little more than a month now. Plants are beginning to reach a foot tall. Started the seeds directly in standard "kegger" red cups which i cut holes in the bottom for drainage. I will be transplanting to a 6" pot once the plants start to show gender. (will also switch to HPS 12/12 at this point) Rating: 5
