Help! advice when to flower

[Fitz87]

Some advice please. Alll plants are healthy, nice and green. They are under 600w hps, just started nutes, from seedling they have been under light for 6 weeks, 3 others were behind and from seedling been under for 4 weeks. Not sure when to flower as I have lstd them and tied some of them down. First time lst, When would anyone recommend to switch 12/12? Are they too short to start flowering? will the stems stretch out more during flowering, get bigger i mean? thanks. 3x bubble kush, 1x power flower, 2x others.

You can flip the plants whenever you want fitz. You could do so now if you wanted.
(12/12)

with what I have here, should I get a decent bit out of it if I switched now. Will the branches get longer and spread more?

What the Temperature like ? Humidity ? What soil are you using ?

I would try & get an additional HPS lamp if possible , look for a used one on craigslist. You have a beautiful garden.The more light the more you're going to yield.

Will the branches get longer and spread more? yes , for the next 2 or 3 weeks from my knowledge

temp is 27-28 c humidity I never bother with but I have 6" carbon filter exhaust and 4" inlet. no sweat at all, very good air flow and circulation. im using biobizz lightmix soil. like I say from seedling been under light 4 weeks some 6 weeks the other. Just want to know if all the individual branches are going to reach and shoot into main colas? I topped and fimmed each one 2-3 times
