Question about changing Kelvin??

Hey got a quick question regarding Kelvin temp..ive been running 14k halides for a long time now(couple yrs).usually change them out every 8 months or so..well I was a little over due umm(11 months)..but ok for the question..now that I have the cree LEDs and not the PCs for actinics,I had to much blue8) .so I went with 10k(same brand,pulse rite)I have good growth with these(14k)..just wondering if I need to cut back my light time for the change in brightness??.........TIA..

 

I cut back time about two hours every time I change the bulbs then ease back into regularity over the course of a week or so

 

yip,that's what I though,figure it couldn't hurt...thanks..
