I want to use this hopper lock system i designed for my skeleton farm to automatically craft bone meal while letting everything else just despawn, but i've run into a problem. I need to keep bones in the hopper because otherwise other items might get in and ruin the crafter. To keep in the bones, i designed a system that keeps the hopper locked when it's low on items. The problem is, no bones can even go into the hopper because it's locked. Can anyone help so the hopper lets items in, but doesn't let items out when it's low?

I think you’re going about this the wrong way. You should use an item sorter to determine which items are bone and which aren’t, then send the bones to the crafter immediately.
This looks like the most whimsy version of an impulse item sorter (2 dust version).
Quick solution for you is to use 2 hoppers. The one on the bottom you lock and unlock with redstone, and one on top of that that points off to the side. The top one stays unlocked and pulls in your desired items but can’t push it into the lower one. The lower one effectively sucks the item out and pushes it into the crafter
