I am trying mainline/manifold for the first time, I have created the 8 main colas, am at about 7 weeks of veg, I am curious if i am suppose to remove the lower growth tips? Do i remove all growth tips other than the 8 Main colas? Or just leave them?

They'll grow into secondary main colas. If your scroging anything below the net should be trimmed up during the strech. Cheers
