My little crispy wave has been putting out a couple of new leaves since I bought it last fall but the new leaves are flat and thin (two leaves in the center of the pictures). Also some started getting brown tips and eventually died :(

I keep it in low light environment in my living room and spray it twice a day to increase humidity level. Is it because of dryness? We have very harsh winter here in Canada and heating makes air super dry...

I would appreciate any suggestion/advise to keep my little plant healthy. Thank you :)
