Help with the leaf curl in my aerogarden. The water pump is currently running on for 60 minutes an off for 100 minutes. I'm guessing it's getting over watered somehow. What should I change the water pump to, to fix the problem? Should I have the water cycle come on more often or less often? I do have an air pump with an airstone in there. Though I feel like I should get a better air stone. like those flat ones that are able to pump out more bubbles.
