Possible manganese deficiency?
I fixed some previous issues and have not been feeding my plants. They are in peat and worm castings and pearlite. About 6.6ph soil, watering with 6.5-6.6 water. I am going to water with nutrients again to see if that helps just want to hear another opinion.

Brown spots/yellow tips after accidentally breaking a blade
Hi! I accidentally broke an older blade from one of her leaves, and after a couple of days that leaf started getting brownish spots and slightly yellowing tips. Is this normal to happen after a broken blade and will eventually die off? Or is this any sort of deficiency? Thanks !

Yellow/Brown/Spotted/Crispy Lower Leaves
What is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.
