I got this beauty about 2 weeks ago and ever since she came home she has had those bumps under 3 of her leaves. This is the leaf that is the most affected. I have been googling day in and night and I cant figure out if its rust fungus, thrips or maybe it is totally normal and I am just freaking out for nothing. Ive never seen the above mentioned conditions in my life so I cant know for sure. I wasn't able to spot any bugs so far. The spots don't seem to be growing and there is nothing on the top of the leaves. Otherwise, the plant looks healthy and is growing new leaves.
Does anyone know what those bumps and discoloration are? Thank you in advance!
