growth during flowering

How much can I expect my babies to grow during flowering. They are 8 to 12 inches tall now. Thanks.

expect double or triple in size

i think it varies alot by strain my last couple of attempts the plants probably only gained another 50 percent of height started flowering around 20" ended up around 30" the ones i have going now have already more than doubled . I also have a similar question these plants i have now are around 4 weeks flowering like i stated above they have already more than doubled in size about 40-42" tall now will they keep growing or do they now focus on bud production ? I have the room if they want to keep growing Im just curious ... thank you

sup guys.
im sure you know but just putting it out there.
light height is your main control of plant height, with new clones hight is usually as high as possible for first 5 days then drop it 80cm from tops then 2 days down to 60cm , then 2 days down to 30cm from tops. try and maintain the 30cm for the rest of its full cycle. You should have more thickness than a long thin stem making less yield.
hope i helped if not only trying to...

I was told that adding Bud Blood during the first two weeks of feeding will slow "the stretch."

I'm currently testing that recommendation.
(I grow in a soil-less mix and feed the plants every 3rd day through bottom drain holes in the pots)
