Please help, leaf tips twisting and curving outwards

Alright quick background:
4x8 tent
2 630w DE CMH
12 plants in 5gal and 7 gal soil pots with roots 707
Watering every 3 days with nutes every other water. Using general organics full line at half dose since they were babies. I’ve seen no deficiency issues throughout the grow. Haven’t given first bloom dose yet, still feeding veg.
5 days into flower

Some of the new growth tips have been twisting and curving outwards. I can’t seem to find any concrete information on this after researching for a while now. Any ideas?

Normally stress of some sort causes it, temps ,light or nutes, looks a bit green for me , lower your dose of nutes, check your environment

Normal to see twisty leaves if you don't stay in the same pH range.
The plant looks OK otherwise, just keep things consistent.

They all look very healthy to me, very green and the curling all suggests to me its a classic case of borderline over-feeding. I'd be somewhat suprised though given your feeding cycle.

I personally feed every time I water, but stick to a 2-3 day cycle as and when the medium has fully drained. This way it is as consistent as I can be and I don't (in theory) shock the plans so much with periodic high concentrations of nutrients, and then none at all. In addition to this water cycle, I liberally mist them (only during veg stage and early flower before any buds start to form) as and when I please just for fun. It's as close as they will ever get to experiencing real rain conditions, and they seem to love it.
