Will the plants be too tall for the tent?

600w Dual Spectrum
0/24 Cycle
10 gallon Smartpots
In veg for a month and now are 9'' tall
Top height of the light in a tent is 6'
I intend to top them two times and veg them for month and a half more,thats 2 and a half months all together before putting them in 12/12 cycle
Will they grow too big for me?

maybe do some LST or mainlining to make sure you're good height wise
