Tomatoes

During the bad weather, we went to the local greenhouse and got 12 Roma tomato plants. They've been in the window seal since... and I'm very new to the tomato world, having never actually grown any before... so these little guys have me worried.

They are just a little droopy. Not all of them but about 1-2 in each set of 4. You'll see what I mean in the picture:

See what I mean. It's just a little... "bendy". I don't know if saying its wilted is exact right description. Others stay up nice and tall though. Definitely color me confused.

I asked in a local group and it was said that perhaps I've been over watering them so I'm going to let them enjoy the sun for several hours today and bring them in and be a little more careful about how much water I give them to see if that helps! :D
