Pistil color after 27 days 12/12 WW photos

[crunchyfrog]

I am ~4 weeks after flipping to 12/12 lighting for four WW photos. A few of the pistils are getting some orange/brownish color to them, one plant probably about 30% of the buds or so, the other 3 plants less than that and one plant hardly any (see photos) . The buds that are colored are a various places/depths in the canopy and do not seem to show any other pattern other than one of the plants has a more buds colored than the others. After googling/searching and reading, I am sort of the opinion that this is normal but since this my first grow, really do not know. I am going to feed them today and I wanted to know if anyone thought there might be a nutrient deficiency or nutrient overload before I feed them or you think there is another problem. Also, do the buds otherwise look "normal"? Thanks!

Looks normal to me.

Looking good to me about 2 or so weeks into the bud stage? Looking healthy

Thanks, any reason you can think of why one plant has more of these with color than the other 3? I started getting white hairs/pistils within a week after flipping to 12/12 would that be 3 weeks bud stage?

crunchyfrog That's what i do count that way as soon as i see the bud site start to shoot up the hairs that's when i count weeks of flower. Nope don't know why different color that's something i've experienced along with others on GWE.
