I wasnt actually running "warm white" bulbs. I was running 6500K,same K temp as MH bulbs.
So far the stretching is limited to much the same as what switching from MH to HPS would give.
I may just switch up 4 or so 6500k into the mix,for the last 4 weeks of flower as %25-%30 blue spectrum tends to give frostier buds.

Thanks for checking out my thread bud.
