They have been curled on the edges like this for a while they’ve continued to feel like normal I raised the lights thinking it was light stress they continued to grow but the curling hasn’t gone away. The new growth is only 3 leaves as well when it was already doing 5 fa n leaves
That curl likely won’t go away my guess would be it’s stress from either heat or light. You can also cut the leaves when you clone to reduce the surface area of the leaves so that less water is lost through evapo-transpiration. Leaves have hundreds of stomata on the underside of their leaves through which water, pulled from the soil via the vascular system (which starts at the roots), is evaporated into the air.
