Drill some more holes in your pots right now, they aren't draining. To start with go about 1cm up from the bottom of the pot and drill a 1cm hole. Do this 6-8 times around the bottom of the pot. (Next time you grow, mix about 30% vermiculite in with your soil.)

Are you adjusting the pH of your water before you put it into the pot?
