Any ideas on this new growth?

New growth sudden problem. Any guidance?

I'm a newbie, but I'll try. Are you in vegetative stage? If so, this looks normal, except the leaves are curlier than the strain I'm growing. What strain?

Looks like over watering with heat stress

Purple crack and pineapple Chunk have the most noticeable changes. Dutch Delight is the other, seems to be ok. Yes these are in 18/6, these are all photos.

Those would cause this ? Very likely candidates. Soil was pretty dry I thought before I added water.
Would you cut off the damages terminal ends ? They are going to be outdoor plants in a few weeks I didn't want to stunt the growth. Clearly I've already damaged them. Temps never got over 80 under T5s
