No, we use tap water that sits for a couple days, and we use general hydroponics bloom at 1/4 strength. We ph test the water everyday. Today the 4 that look healthy started showing roots, so it seems the water set-up worked fine with them. (you can see pics in the indoor growing forum)

It's the Northern Lights #4 that have the issue, the Northern Lights #2 are healthy. Their not dead, and are sprouting new growth, so I guess im more confused than anything.

Thank you for your advice, and im going to look into cal and mg issues!
