Man am I confused.My AUTO ZKITTLEZ girls are flowe...

You say this is an Auto Flower? If yes there is no need to change your light cycle. Auto flowers pop based on their own internal clock. They will flower when it is their time. If they are flowering treat them as such. I had a Cafe Racer flower under 2 45 watt Root Farm lights I use for seedlings. I later ,oved and kicked up the light and she is absolutely thriving now.

what ? You dont change autos to 12/12 they have either 18 all the way through or they have 20 on and 4 off or even 24 hour light autos by definition flower by themselves you have no control over when she flowers so theres no need to stress her with a different light cycle thats why alot of growers grow autos in thier mother rooms cause they dont need switiching :) using both would stress them unneeded. Best of luck anyway :) blurple light is a really good specturm to grow with i dont really know what you mean by veg and bloom if your talking about the switches on the light well i dunno but blurple light is blurple if your adding red into it then I dunno it should be in there anyway

yeah, use both

Your probably gonna want to keep them both on, having only one on will decrease your watts
