Help! Accidently fed my plant moldy ferts

Allright so my plant is ablout 5-6 weeks into flower and I had some ferts that i made 4-5 days ago that had mollases and some fox farm tiger bloom, stupidly I figured it would be fine to use then again so without checking i poored some over my plant, well i look down in the gallon jug and see mold in the bottem. What should i do? My biggest concern is that the roots get moldy and then it willl get my bud moldy and ruin it. Should i use some peroxide with my water I have heard of people using it before, or should is just do a flush with normal tap water? please any imput welcomed.

Should be fine. Make sure you have good 24 hour fans going till they're finished. If your really concerned you can mix up a bottle of hydrogen peroxide and just mist the top of the planters. That'll kill any mold of fungus.
