Topping and veg time

Hello to everyone on RIU!

I am 2 weeks away from finishing this run and I am already planning the next. As I am not a very experienced grower, I want to try and experiment with different growing techniques till I find one that suits me well. For my next run I was thinking about trying a mainlining (topping 2 times, 4 colas). for the first time. Problem is, I don't want to veg my plants for more than 4 weeks (exactly 28 days, say 30 at most). Would topping 2 times be possible in this veg period? What else I have to take into consideration by doing this? Am I missing something? Please let me know your thoughts!

Here are some pics of my actual grow...

Looks like they have longer than 2 weeks to go. Good Luck.

Yeah I agree, a lot more than to weeks.

You could top once and then lst the colas which wont stall them as much.
Its just something you will have to figure out because so many variables will affect your growth rate in veg.

4 weeks at least before ready.

I doubt it, maybe in coco
