I'm almost 100% sure your plant's problem is too much water (not too much fertilizer). But on that note, I thought I saw a tell-tale Miracle-Gro round fertilizer ball in one of your pictures. If that is the case, then you'll have to be careful to not give them too much fertilizer as the mix already has some in it.
Keep a fan on them - that'll help speed up the evaporation from the potting mix. If you can slightly raise the containers so some air flow can get underneath (where, I assume, there are holes in the bottoms of the pots), that should also aid a tiny bit in drying out the over-saturated growing medium.
Your plants can recover... but the affected leaves will not. The twisted stems/leaves will stay that way. The leaves with the dying tips might fully die off. But the future new growth will be normal if the moisture problem is rectified - so there is hope!
