Should I leave these flowers or prune.

[Victoria]

hi, I´ve built the 11 plant system and I have some tomato plants growing in grorocks & Flora series. I put the tomatoes in the system less than 2 month ago. The tomatoes don´t grow very much (are 7 or 8 inches high) but they started flowering already. Should I leave these flowers or prune. This is my first attempt with hydroponics. I'm in Mexico City, lots of light and warm weather, not very hot yet. Thanks a lot, Victoria victoria@quetzal.innsz.mx
