I used hps 400w for veg. stage im planing to use it for flowering also.

There is something else, my plants pre-flowered can you determine are they females?

Here is a pic as close as i could get it
Those look like females to me, and you keep saying you use 400w for veg, but what bulb are you using? MH or HPS? and there is nothing you should do for switching but set a time for the change, I'd recommend 8 a.m-8 p.m .

Oh and yeah, try to give them more P than N and K during the flowering time, didnt know if you knew because you asked about what you should do and all.
