I had to go out of town for 11 days and come back to this. :spew:

I had mixed some 400 ppm nutes, ph'd 5.6, for my friend to water them.

They were also dry as a bone when I got back. Although over a gallon of nutes were used.

They were growing slow before I left, but looked healthy. now just a month old, are dying.

This is my first grow using a medium other than soil. I plan on going to ebb & flow after cloning.

They are fem seeds- ppp & supergirl.

t5 lights.

humidity good, and temps 65-75.

Is this green stuff algae?!

THANKS FOR ANY HELP
