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).
