What's wrong with my plant please

I don't think this is the problem but I have been neglecting them for awhile now & just water the top soil instead of a full soak when they need water, then do a full watering soon after. The non-dead leaves at the bottom seem to be weak and fall off easy. Thanks in advance

The white splotches on the leaves look like thrip damage. Check the underside of the leaves with a loupe. At 40x, you can see light brown colored deposits on the leaves as well as mature thrips. If in doubt, go to 60x and scan the underside very slowly.

Looking like an insect pest. Really good magnification may be required to see them.

So I checked over my plants & it seems to be an insect problem. I don't think they are thrips though although they somewhat look like them. I've had thrips before outdoors & they were really easy to see especially adults. These plants have been growing for many months now & I noticed these bugs at the start just didn't seem to be many worth caring about. There are more now but I see no adults. I wish I could take a picture of them, I will try. Tyvm
