I think you’d been better off using just the coir as the bulk substrate. Manure can be tricky if not thoroughly pasteurized. Coulda been slightly bacterial spawn too mixed in with bacterial manure. Then you add covering with paper and a bacterial bloom can happen quickly. I can’t be sure but it might also be hot this time of year where you are and it’s a recipe for disaster.
If your substrate is at field capacity, don’t worry about some evaporation… it’s suppose to happen. Evaporation off the fruiting surface is a pinning trigger. One thing I learned very early on is that it’s riskier to restrict FAE to almost 0 during any part of grow. People use to cover their tubs in blankets and garbage bags.. horrible idea. Bacteria thrives in anaerobic environments.. especially hot ones. It’s much easier to add a little water down the road if your sub dries out too much or even let the flush ride and get a not-so-great first flush and rehydrate to get that bangin second flush.. at least then you have a healthy sub that’s ready to throw off more fruits right away with fresh water from a couple heavy mistings
I say let it ride and give plenty of FAE. Scratching the surface can just push surface contamination that landed on the top deep into the interior of the sub where the high nute grain is which wouldn’t be a problem with a healthy sub but yours sounds like it’s stalled and already unhealthy
