Thanks guy's .
I didn't think it should be that high. The closet I keep them in stays between 75 and 80 about 85 close to the lights. I have vents to AC but they need extra fan to get a good air flow. I have cloned a bunch in the rockwool with success. This kind of had me cause the seedlings are doing great. Well the stuff I thought was algie is maybe a pump problem. The stuff is kind of oilly but not quite with a little sand in there ? I'm going to clean it out and try again. I'll post back.
