Ready to Flower or Not?

My plants have been in vegative growth from seed for nearly 5 weeks now and im not seeing pre flowers but however I am seeing alternating nodes but only on branches not on main stem? is it still ok to start flowering soon or should I wait for alternating nodes on main stem first? all plants are between 11" and 14" tall and very bushy as ive vegged them under 600w 7200k metal halide.

You can flip them whenever you want

sorry should of made it more clear... have they reached sexual maturity ??

Some plants will do that regardless of the photoperiod, while others won't start to show preflowers until you induce 12/12 or 13/11 or even 11/13

ok so you think they big enough now to still get a good yield from a 600w hps?

Honestly you could flip now if you'd like, personally I'd top a few or lst and wait another 2-3 weeks myself

ive already fimmed them and 3 of the plants now have 6 tops so I might just let them get to 16" as im restricted to 1.4m height In my grow room
