Twisting new growth? Can’t handle the lights? All other leaves good

Or is it something else?
Plants seem to be overall healthy, temps dipped abit but sorted that, don’t see why it would affect just the tops though if temps was the case unless it’s temps from lights, but isn’t too hot tbh.
had this a few times, but don’t have the memory to remember haha, this is a new stain I’ve not done before either, there’s two strains 7 x peachy Mac and 1 x incredible bulk- the incredible bulk seems to have zero twist, I’ve heard that plant is resilient so that could be the case..

input appreciated

2 x 1000w gavitas

1 x1000w Zeus pro.

1x 700 lumii

temps running at 75 humidity 50.

feed canna A canna B.

vegged for 1 week from clone, yes one week

50litre pots under the Zeus,not kept count on the flower but think it’s been about two weeks, so three weeks in all from clone,

plants are bushy and never usually prune as I get solidnuds right down to soil, but took abit of this time as they are fucking animals

hopefully they’re all good and it’s nothing or something little, seen it a few times, when I’m running this much power I can sometimes get smaller budson the tops andbigger underneath

Pics would be quite helpful.

Twisting leaves are a sign of pH problems.

Taco'ing leaves are a sign of humidity problems.

Best I can do without pics.
