My 1-month old hydroponic cherry tomato plants which I am growing in an Aerogarden have developed strange "growths" mostly, but not entirely, on the bottom edges of the leaves. I do not see any movement in the "growths", but am unsure what they are and how concerned I should be. Any assistance would be appreciated. Photos are attached.
