How much longer to Veg?

As long as you want my friend they are your plants though if your looking to scrog then I would do some training first and let them veg upto the net training as you go trying to guide branches into every square of the netting hence filling all the space in your grow room take a peak at my SOG grow for tips but keep in mind plants can double or triple in size in the strech process so keep that in mind. What you wanna be doing now is training my friend if you wanna build a nice canopy with all the plants if you want to keep them seperate and grow normally and keep them small I would switch the lights in about 1 week but personally I would veg a plant for atleast 6 weeks before considering to flip it. I think a larger plant can support a larger harvest. Though not saying small plants cant yield they can but yeah if you have the space why not fill it get the most for your money :) more bang for your buck hahaha best of luck anyway bro they all looking nice and healthy :) 👊
