Plants won't flower!

Plants won't flower!
I need some help. I have sour diesel and super silver haze that have been in veg for 5 weeks and then switched to 12/12 lighting and have been in flower for 6 weeks. I have lots of pistels but no bud.
Growing in soil, using greennplanet nutrients, temps are 76* on 63* lights off 45% humidity. I have no light leaks

You are in flower. @ week 6 I'd say your light is too weak, or untested genetics.
-Where did genetics come from?
-What is the light source?

I think genetics might have something to do with it, those are 2 longer flowering strains as it is so if you got some odd sativa phenos or something that might be some of it.

You need to step up your light intensity seems to me. What lighting are you using??? Keep in mind you are running a sativa with the haze line. Need lots of light to flower well. And they can at times take a long time to take off. But at 6 weeks looking as sparce as they are I would guess lighting is your issue. IMO

Using spectrum King 400 led. It was off the charts with an analog light meter

Thanks for the help guys. I will post an update soon.

You need more light mate. The problem with LED is the area coverage. The light needs to be right on the plant 5-6 inches at the most and raise as the hight increases. You need another one them bad boys over them especially sativa strains. You looking at 12 weeks from seed the strains you listed, clones may flower slightly faster as they are aged already.

Cut watering right down as well ration it and only water when the soil is almost totally dry. Having waterlogged soil slows flower production and slows growth in general. Just lift the pots slightly off the ground see how much they weigh or get a moisture meter.

They are 2 things you need to get right. Can see a little hooking there on some of the leaves. Light (lack of or too much) and over watering are the most likely causes. Most people get the PH right, I know people that have never checked the PH as most products are the right PH anyway. Peace and good luck !! GJ
