If you keep a 2 - 3 inch gap between the the plant and light that's maybe 9 inches left so not too much room to work with. As you move everything up and there's more foliage the temps will also rise a bit so maybe keep another inch spare just in case. Expect a growth spurt just after you switch and a bigger spurt just after they show sex. I'd guess 2 weeks more good growth and I'd be switching them over.
Try to have all the growing tops at an even height when you switch too. It will save bother later on.
