Estimate veg time in these pots? [PICS]

Due to space constraints I have opted for 4.5L (about 1.2 gallons) pots for my 6 plants under a 250w in my closet. My concerns are that if I veg them for too long they'll get too big for their pots and get rootbound halfway through flowering. So I want to be sure to veg them just long enough before switching them to flowering. I know I can start them flowering from seed or whenever I want but I still want to get the most yield out of them for my conditions/time.. I also can't let them get taller than around 2.5ft (not including pot).

Judging from this info and these pics, can anyone give me an estimate of how long I should veg them for before switching to 12/12?

PIC1: top - day13 bagseed, day7 white widow
bottom - day6 mama mia, day6 white widow
PIC2: day13 bagseed
PIC3: day7 white widow
(all dates from when they sprouted above soil)

Thanks for any advice!

I would say veg for 30 days and then kick it in to flowering. Looks good so far!

That's what I was thinking before but they have really been growing fast these few days with the sunlight and all and I may have to put them in flowering sooner.. I might just go 10 more days or so. Anyone else with any input on this?

yeah should probly veg plants for about a month at least grow them probly 2 footamaybe 3ft mite have an half oz from each plant , if your worried about them being root bound buy pots a little larger and add a bloom mix of soil 2 the pot and then u wont have 2 feed it for a month just needs pure water, then there will be extra space for the roots and your yeild should increase

This clone vegged from July 1-Aug 15
Topped twice, supercropped, and lst.
It's in a 2Gal. pot and is 10" tall.
It's flowering under 250W hps.

Thats great what you've done with that one. Trained to bits! I'm not going with topping or cropping as I don't have time for them to get stressed and recover, more likely to go LST. When's a good time to start?

I would start once they grow a few more nodes since you don't have a lot of veg time in that pot.

As soon as you can grab some stem, and no bud/leaf you can lst.
Easier with young limbs.
