First time. In all the hours of research I have done I haven't seen discussions about nutrient water color and or film deposits. Please take a look at the pics and tell me if this is normal. The color didn't alarm me but the film on the pump, and I assume other parts in the system, makes me question my water. I cant imagine it's algae already. It is RO water, 500 PPM Cal Mag, 500ppm GH three part. It's been running for 3 days. I have already stressed my plants twice from pulling noob shit and I just got them healthy again.
