The leaves have been limp and weak for awhile, but now there's also brown/black spots (with a little yellowish edge, I'm not sure if that helps). Even the leaf that's coming out now is limp and with these spots. There's also little silver/yellowy spots (they're like a yellow-grey and in the sun it looks more like a silver/white-grey colour), I think that's how the brown spots started but I can't say for sure.

Any idea on what to do? I haven't had any strong sun in like a week, so I don't think the leaves are burning from sun exposure. The only "pest" I can find are those little flies/mosquito's (I don't know the English name, but I've read up on them and they aren't really dangerous except on seedlings).

You really can't take a guess without pics?

Because I don't have a cell phone/camera. However, I did find a picture that perfectly shows how the spots began:
Target Leaf Spot | Vegetable Resources

The top picture is exactly how the beginning spots on my leaves look (although when you zoom in, the spots look less "solid" and more "spotty", but that could just be me not being able to notice it on my plant). Mine only have it in a few isolated spots (Near the leaf edge and beginning of the leaf, tips don't have them and are already yellow/brown), and there are still a few leaves unaffected. It says they turn into "necrotic lesions", and that could very well be the brown spots that developed afterwards, or those could be completely unrelated.

It doesn't seem to be the disease listed here, because the brown spots don't actually develop into holes. The leaves just shrivel up and die, and the older the leaf the further it is into this process. Some of the newer leaves barely seem affected, and the oldest few leaves are about to fall out and are completely brown/yellow. The new leaf that's coming out has the biggest and most of the brown spots but none of the little bronze spots, the others just have solid brown areas with a few of the little bronze spots I posted a picture of. The 2 newest leaves that were already out have brown/black tips and the little bronze spots but not the big brown spots that the new leaf has.

And now the new leaf's tip is basicly all bent over and pointing down so it's getting worse by the day.

Any clue at all? Is it a disease or more likely related to watering or sunlight? I'm not sure if taking it out of the pot to check for root rot is any use, or if it's definately something else.
