Could be neut lock from over feeding if your feeding everyday and using a soil the salt content will build up in your soil and lock all neutrients out of your plant in your roots. You need a strong flush to wash out your medium and start over with your feeding plan! Ive had that very same look to a plant some years back with photo plants if your soil is taking 3 days to dry its too dense and your plants cannot breath through their roots. Which also causes build up in the soil. Adding more neuts will only increase the problem unless you flush first.
