This is the 2nd year I have grown tomatoes. I am a young gardener, with a balcony garden in pots. Last year went fantastic and produced many tomatoes. This year I have 6 plants I started from seed indoors. Three Pomodoro San Marzano Tomatoes, and three Pomodoro Scatolone tomatoes. They are all planted in plastic pots with store-bought potting soil.
I just transferred them to the pots and put them on my deck a few days ago and today I noticed the leaves were changing color. I am completely new to this and don't know what it is or how to fix it. Any help would be appreciated! (My balcony garden is the only place it can be, I live in an apartment but sunshine is not an issue)
