I had the same thought (about water sitting out and changing the PH) so I tested the tap water as fresh as I can get it.

I transplanted about 5 days ago. I will water and test runoff for the "issue" plants now.

Thanks again.

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
