We cant answer that question. How much over head space do you have? Those plants are going to be 2-3 times bigger than that by the end of flowering. They are untopped too so they could get pretty tall. The good thing is you have t5's. You can get them realllllyyy close to your plants and they put off a blue light, which will help reduce stretching.. My 1000w hps needs to be like 2-3 feet from the plants or else it burns them.



Also you will want to consider how much you want to yield? Longer veg time= more buds in the end. (but monster plants!)
