Hi all,

I am a plant newbie and need your help. I just got a new plant delivered from a local store and noticed that old leaves has some white dots on them, while the new leaves are fine and clean.
I thought it's a water residue, and tried to wipe it, but although it cleaned the leaf a little, the dots remain. I reached out to the store and sent them images. They told me that it's the plant being sensitive to hard water, as it prefers rain water.
I really like this store and I have quite a few plants with them, all in perfect shape and health. So i have good faith that they wouldn't sell a sick plan.
However a bit worried about these spots. I checked for any signs of spiderwebs or any signs of insects and don't see any. The back of the leaves are clean and seem fine.
I am just wondering if it's indeed sensitivity to the water? Or it's something else and i need to treat it? I have other plants and i don't want them to get sick.

Thanks!

I don't think it is a serious problem, but I don't like the store's explanation. If it is sensitive to hard water and it is brand new to you, then why were they using hard water?

I am sorry it took me so long to reply. I agree, I found it a bit strange as well. For now it seems to be fine, although with these dots, but at least it's not rpogressing / worsening.
So I guess I will see how it goes on a long run..
