I tried to search about this specific spots, but couldn't find anything relevant. But I'm also new to plants and gardening, so I probably don't know exactly what I should be looking for.
I got this dracaena lemon lime a few weeks ago, but it started getting a few brown spots on the leaves, as you can see above. I'm not sure what it is, does anyone know and know how to deal with this? I usually water once per week since it's been hot, and spray and clean its leaves too.
