I made some extra 5 gal buckets of nutes which I left in my tent while I was gone for 5 days. I has been exposed to the light (18-6) for this time and I can see a film and may be something else on the surface now. Is this possibly fungus? I'm thinking I should just toss it and start fresh. Anyone else run into this situation? I'm growing in coco and perlite. GH Floranova.
