New leaves are twisting, any ideas?

So I've noticed on a couple of my plants in my tent, the new vegetation is twisting/curling. If you have any experience dealing with this or even if you have any input as to how or why this would happen, feel free to drop me a tip. I would really appreciate it!

pH is the first to check.

Hmm, kinda looks like early Russet mite damage...
Still, kinda young for that yet...

Anything change in the grow environment? Feed? Any changes at all.
New strain or one you've been cloning?

Might be sure your micro's are at proper levels..... Fe and S

Its GG#9

Have temps and RH stayed consistent?

I added 600 watts (LED) to my tent, temp is 23°c with 40%RH

Not really, I upped the nutrients a little bit. Other than that it's been consistant

What does that mean lol

Just let them mature a bit more, The plants are (were) not that old yet.
They'll get better looking.

For the most part, rather normal.
