I'm not sure about the dried ends of the current new growth. It could be under watering, as new tender leaf growth requires more irrigation than the mature foliage, due to the higher levels of transpiration (losing water) then mature leaves. The curling and deformation of the larger mature leaves happened way back when they were just forming. It was caused by insects such as thrips and others feeding of the new leaves. Tender new growth is dessert to insets.
