My first indoor grow leaves are twisting please help

I have two plants. Got them as clones. I thought they had spider mites a few days after I got them home. They had tiny white dots on some of the leaves . But I never witnessed any kind of insect on the under side of the leaves . I googled and googled that's what I decided was the issue . So I treated them with a alcohol water mixture sprayed them for about 2.5 weeks then stopped the white dots stopped and I have not sprayed them sense.
The leaves are twisting and there very dark and meaty. The texture is thick and odd . The temp is 76 degrees. I feed water mist and love them. there on a timer my light is good there's fans in the tent I'm just not sure what my lady's need and I want to be successful at this grow. I enjoy watching them grow and change the whole process is super amazing . So trial and error sadly. Any help would be appreciated. But I need a definite diagnosis. There's so many different possibilities that I'm unsure which is the right one . I don't want to kill them.

They look over watered. Stop misting them too, it will cause burn from the lights.

Overfed.
Either your soil is too hot, or your putting something in the water, they are full in N.
Burnt tips, not a good sign,
an idea how tips are supposed to be

Look carefully, no yellowing on the tips, the purple you see is fade they are F35
Anyway, I suggest you transplant into a basic soil mix with ewc and normal tap water or RO if you have access to it, 1 week and it will come back to normal.
