Curling leaves in vegetation

These leaves are twisted and curly but look healthy otherwise. Is there something going on I need to address or just a freak like me?!

pH issues might be contributing to a nutrient deficiency. Or it could be a boron deficiency, twisted growth is often an indicator of a boron deficiency. It looks like you have some other issues on other leaves as well, the yellowing at the edges, maybe signs of a potassium deficiency.

Yupper, curling leaves are generally the product of PH imbalance.

PH 5.8 for hydro
6.5 for soil
