what's up 911? don't you have a post in the plant problems section already for this problem? why post one in the growing information section? people respond to posts at their leisure.

anyhow, i see you are in rockwool. did you presoak it first in properly pH'd water? rockwool can cause pH to run up.

your rez water temps are a little high. i'm a dirt farmer, but i think 70F is a good temp. i'm sure somebody else will chime in (perhpas cigarettes42?) this high temp could be contributing to the algae problem.

what are you using for your rez? is it clear or opaque? are you running in a sealed room?
