Hello, I’m growing tomoto’s in hydro for my first time. I have 4 tomato plants, One is about 4 ft tall and the other 3 are about 2 ft tall. The big one has started giving a few flower and it’s looking really nice. My problem is I’m not sure when to switch the nutrients to flowering phase. Should I do it when I first start seeing a few flowers or should I wait til all the flowers are open and ready to be pollinated. Any information would really be appreciated. Next is cucumbers, herbs and peppers.
