What's up Jack, plants look pretty normal... Only thing I noticed when looking over your conditions was your light distance was stated at 11 inches. If this is correct it is probably causing heat and light stress that is slowing your growth down. It could also be why the leaves look slightly lighter than normal but could just be the picture.... if you're running 250W during early veg you should have more like 24-30 inches clearance for the light. Hope this helps and happy growing ✌️👊
