Blue Dream, advice needed.

I have a nice blue dream mom, and several clones taken from her. The clones are currently around 6 inches in height.

What I need is a little advice from those that have grown this strain befor.

My indoor setup:
(2) 400 watt mh + cfl for veg, (4) 400 watt hps for flower.
soil grow, foxfarm.

What I need to know:
How much does this strain stretch durring flower? I would like to keep the finished plants aprox. 3 1/2 ft. to 4 ft. At what height do you flip them?
How does this strain react to nutes? I have some strains that soak up whatever you throw at them and others that need a very minumum of nutriants to be happy.
Should I top, fimm, LST, or just let them grow however they want on their own for the best results? ( I generally do not do a sog or scrog grow, although I may if this produces the best yeild ).
Anything else I may need to know regarding this particular strain.

Thanks in advance for any help.

I have only heard of that particular strain. I would go with the Marijuana rule of thumb on any plant im not sure of. The rule of thumb on growing is grow withe what you have. Meaning your knowledge of prior grows. Here is a link that may help. Its another guy growing the same. https://www.rollitup.org/indoor-growing/161620-blue-dream-advice-appreciated.html

Got 6 i started flowering today, I have been told 300% stretch, ideal for SOG growing.

3x stretch is about what I figured, but I thought I would best check with others who have grown this strain.
Thanks again
