Three days ago I started my first hydroponic Atwater DWC-Top Drip, with Frog Farms three bottle Nutrients and PH kit from Atwater. I measured everything perfect and my PPMs were between 700-800 PPM and my PH was perfect. I am trial running for a few days without a pant to see if everything ran okay. Well today I noticed a hard white film on the lid, almost looks like hard water spots. And the inside of the bucket has a white film sticking to the bucket only where the water is in the bucket. Can anyone suggest or tell me if this is normal?
