I have an Aerogarden plant that's about 3 ft. tall, to the top of the canopy. First time I've tried this and something doesn't seem right. Even though full of leaves and tall there's not one sign of a bud. I notice a couple of little tiny sprouts coming out of some of the branches at the joint of the stem but that's it. About 3 1/2 months old. I appreciate any time you give to reply and thank you in advance.
