When you're doing cakes like that, you need to have your rh as close to %100 as possible at all times. Since you're using a shotgun FC (with too many holes I might add), don't fan so frequently. That's lowering your rh and by the time it reaches more optimal levels you're coming back to fan it all away again, it's like an endless cycle of never achieving/maintaining your rH.
Suggestion: Get an airstone and water pump. Add more perlite, so you have 3-4 inches in total, then add 1/2 or so of water, submerge airstone under the perlite.
Also, if you lay the cakes on tinfoil squares, spores wont drop all over your perlite and dirty it up.
