Yeah, it's quite easy to see which stuff is from the medium since it tends to float, whereas the megacrop tends to settle. The gelatinous, slimy cloud in the water leads me to believe there is an algae issue.
Keeping an eye out this week to see how bad it gets and possibly modifying the res to be more light proof.
For now I just upped my pool shock from 25ppm to 40ppm we will see how things go.
I got 30% hydroponic grade h2o2 and plenty of calcium hypochlorite to sanitize an issue should it arise. Fingers crossed it was just week 1 blues and this won't be an active issue as I dial things in.
Also, no progress on seed #5, thinking it might be time to cut losses and try #6. The only thing I'm doing different than previous germinations is not adding h2o2 and/or b1. I might go back to this method, if it ain't broke don't fix it, right?
