When to switch lamps?

Hey,
The issue of lamp switching from 5000k to 2100k, HPS, lamp made me question at what time is best to do the switch.
Now taking in consideration that i am growing indoor, White russian mostly indica strain, with 2- 600W HPS and 1-400WHPS in grow tent, having 17 cloned plants at 45 cm height, feeding with guano bat dung and advanced nutrition set from Holland,.... my doubt is that; if i switch now to 12/12 by making it 32 hour darkness to speed up the switch....and simultaneously switching the bulbs, i am afraid it does make the growth almost completely stopped.
My previous growth went from 45cm to 55-60 at the end of flowering. which ended with not such big yield. I have had completely healthy plants but with relay slow grow rate during flowering.

So did my change to 12/12 with drastic darkness of 32 hours at first, and 2100k bulbs made the plants almost stop from growing in flower,??
would love to hear the thoughts on what i might improve to get ideal conditions.
