kush critial purple wreck

I made a scrog net I use 1/2 in PVC I made it 3 1/2 ft all way around cuz my tent is 4ft x 4ft sobit fits nice but I made the legs which makes the height and it is 3ft so my plants will need to veg a good bit to reach the net .I usually veg 4 weeks then flip my question is Should I cut the legs...
