Switch from HID to Fluoro 3 weeks into flower?

Hey all. I just made the switch from HPS to 8 lamp t5's (4ftx2). Heat and hydro were out of control, so, these lights seem to be much better(running in the mid to high 70's as oposed to 97 degrees!!)
My question is: I have some girls on day 26( GHS Chemdog). Will the switch hurt them part way through flower? I have the 6500k bulbs in cause my local hydro store won't have any 2700k in until Thursday next week, so will they be ok for a few days under the "blue spectrum" after that long under HPS? I also have some that are only on day 12 ( BF Bluecheese and RP Kosher Kush) of flower, and I'm asuming that they'll be fine with it. I've included some pics. This is a legal grow under the MMAR regulations.
Thanks in advance for any input.

As long as they are getting the correct light times still you should be ok.

Test it and find out, maybe you'll somehow increase yield

Your not going to increase yield but loose some, the only benefit of using 6500k is better quality in potency and taste

I'll have the 2700k's in soon anyways, but, better potency and taste souds good......

I just did this. About a week ago I moved one plant from my 4x4 600w hps bloom tent to a new 4x2 bloom tent with a sunblaze 48. I did a lil lst to even out the canpoy. The move was made at 2 weeks into flowering, plants healthy but buds are def smaller then the hps tents. Im running 50/50 blue/red bulbs.
