When should i flip to 12/12?

i've got a few strains in my current grow. my o.g. kush 18, blueberrys, big buds, and northern lights are taking off. most about 8 inches tall. they will be 4 weeks from sprout on monday. in 3 gal bags under 2000 watts metal halide, and seem to grow 1/2 inch to an inch per day. can't seem to find any journals or grows with this strain from seed from t.h. seeds.

my chocolate chunks however (pure indicas that they are), are about 5.5 inches, but super bushy and on the 8th node.

can't seem to find any journals or grows with this strain from seed from t.h. seeds.

if i flip to 12/12 next week, will i still get a decent yield from this strain?

feel free to check my journal:

This is the problem with multiple strains started at the same time. I have done two strains together and started the one I knew would be smaller a week earlier so they could flower together. At this point it's a trade-off for you. If you have the vertical space for them I would let them go to 5 weeks or more if you want. No should, your choice.

it is recommended that you wait till they get at least 12 inches tall. but 2 ft would be a good height to switch to flower. that way you get what you paid for assuming you bought the seeds

82 days before switching here from seed.

id say up to you but i always switch when there 2 feet

my room is only 6.5 ft tall. pots about a foot tall, as well as the reflector. that leaves me with roughly 4 ft of growth. assuming they triple in size, then i can only let them go 12 inches tall max, right? hopefully i can get another 5-6 inches out of them in the next week, week and a half.

n-e one know any good stretching techniques?

if your short on height why stretch em?

so i can even them up wit the rest of my canopy, i guess i could just use booster seats though....
