Leaf Deformality

Hey guys,
Right now I am experiencing a weird situation with my DS plant, and its beginning to spread on several leaves. I removed it from the grow room into quarantine, because I read many sources saying that it may be TMV, but others claim on other threads that it's not really something that happens in cannabis. I just wanted some confirmation.
It is Death Star strain.
Right now, I'm using roots organic soil and am in my second week of flower.
I use the AN PH perfect line
I am also battling fungus gnats, but they are pretty much non-existent at this point, (Finally, took a month).
I do not PH my water anymore since I am now using AN right now, and it's not needed with the PH perfect line.
So far, none of my other plants are showing any symptoms and hopefully it stays that way.
I have temperature issues the first two days in flower it was 85-90, with low humidity of 25-30% then finally went down throughout to 75-77 with lights on and the humidity has been 35-40%.

Can anyone tell me what would cause the leaf ends to hook like that? I've always sprayed the leaves with TAKE DOWN and Neem OIL. Just FYI!

Hello Thaii.
You said they were sprayed with a solution right ?
Spray apps can damage and are Phytotoxic and can burn foliage, that may be the only problem you may have, they look pretty good, I see the big ridges between veins notice the curled leaf fringes that signifies heat stress, and could be salt build up too.
Cal-Mag is the usual problem, but as I stated it just may have been the heat.

good luck keep up posted plz.

Can we see the whole plant?

They look good. I folliar with neem and protekt also. The curling heat stress. Dont worry abought deformed leaves. It happens. Think of it like an ingrown toe nail. Just something that happens sometimes. I notice it more when they are growing fast.
