Nutrient deficiency? PH? Humidity???

Hey so I am having some issues with my plant. It started out beautiful and perfect but now is beginning to show some strange signs in new growth.

In the photos, arrow A points to the new growth having some grayish sort of a rusty looking spot on it, does this mean something?
Arrow B points to this deformed leaf. On that set of leaves, each leaf is folding up and I am curious as to what would cause such deformation.

Temperature is 75-85 degrees (putting an exhaust fan in tonight). Humidity is at 35% (I'd appreciate some suggestions on increasing humidity!)

It's in fox farm ocean forest with extra perlite, drainage is perfect, watered every day or every other day based on soil moisture. I put in a little blood meal and a tiny bit of dolomitic lime. It's under t5s. This is about day 25.

Also, on a new leaf that had been growing, the 4th leaflet on the 5 pointed leaf became brittle and fell off when touched. I wonder if this is a sign of anything.
