I agree with what is being said. You likely have a few things here, but possibly connected.
1- if your plants are root bound, that will give you issues. A good rule of thumb is 1 gallon for every month in the soil. So if you veg for a month and flower for 2 months, a 3 gallon pot is ideal.
2- There may be a nutrient deficiency starting by looking at the yellow / burning borders on some of the leaves. Usually that would be potassium.
3- The roots aren't happy, which can cause the taco of the leaves, nutrient deficiencies and stunted growth.
4- Taco leaves are usually a sign of heat stress (light to close / intense) or a sign of bugs, which doesn't seem likely here.
How long have you been in the pot and do you check the Ph of the water you input?
