First grow 6ft trees?

on my first grow here I veg'd two females for two months on 24 hours light under a 600w HPS bulb. Plant height is already 28 inches and I'm on day 3 of Flowering. Estimating after the flowering stretch my trees could get around 5-6ft tall please leave some comments guys thanks!
