well i noticed i was over feeding and over watering, also i had them with 24 hrs of light until two days ago. I allready flush them to get rid of the excess nutrients and stuff and i changed my lights to 18-6 hrs. so i hope they get better now. its my first indoor grow and i couldnt set my hydro kit up, so i decided to use soil. imagine what would have hapenned if i would have used the hydro kit wich is more dificult.
