plants are going to start falling over

[Brett]

Thanks for the answers Ron I have a few more though..... i'm a little worried my plants are going to start falling over.... Again I am growing tomatoes and they are 2 to 3 weeks old. The water was getting dirty and i took the plants and put them somewhere so the water could drain out while i cleaned there tank.... i left them out of the tank for the day so the dirty water could drain a little and in the morning i would feed them some fresh new water. I came home this morning and the rockwool was still water but half what it usually is and a few plants are falling over a little so i poured some reverse osmosis water over them... no minerals and a few more fell over.... One day without any new water is that not good? they still had water in the rockwool... I propped them up with bottles till the morning. Will i need to put up sticks or something for them to grow against they are still real young and other tomato plants i have seen looked like they didn't ever need to be held up. Any thoughts? If it helps any i posted a few messages up from here
