First time grower, is this mold?

I recently noticed this white film forming around the shrooms and I wonder if it is mold. I am afraid that I fucked up some steps at the beginning and I don’t know if I should throw everything away and start over or if I can continue. If it is mold, does it ruin the shrooms or are they still edible, maybe after some deep cleaning? Thanks so much in advance for the answers!
