Does anyone know of a trick to get dill to grow well? As you can see in my Kitchen Herbs Thread, the dill isn't doing that great. This is the 2nd system I've tried to grow it in - the last one was a F&D system. Both times it sprouted, and both times it's withering at about 2-3" tall.

In looking at the Kitchen Herbs, could nutrients be too limited? I add some liquid trace fertilizer about once a week, and I feed the fish twice a day. In all my time in the aquarium hobby, I've gotten used to going by how things look to determine if anything is wrong... might I have to break out a test kit? I think the only one I have is Nitrate, would I need to test for P or K?

Thanks!
