NB: I possess very little plant knowledge.
I recently purchased this beautiful QLD Bottle Tree from a reputable/fairly boutique indoor plant store who had been caring for it for several years.
I have it placed in my bedroom which has an opaque ceiling/sunlight directly above it. Ventilation is also fairly limited. The amount of sunlight seems roughly the same as it was in the shop.
I've noticed that about half of its leaves have developed this whiteish colour disfiguration. Any ideas as to the cause and cure would be hugely appreciated! Thoughts so far would include (a) Not enough sun; (b) insect; or (c) missing nutrients and needs a feed.
