Okay, few questions and tips.
I can see you have a light problem. Might be too close. Can tell it by the size of your plants.
You didn't fill your pots enough... Maybe a little root bound is starting to show off.
Did you feed them with nutes from day one ?? Depending on your soil, you can actually feed your plants for 2 to 3 weeks without nutes. And then slowly introduce them 1/4 of the normal schedule during veg and 1/2 at flow.
