yellow bud leaves?

hey my plants r 9 weeks wit the light on 12-12,and the bud leaves r turning really yellow,but the hairs arnt turning red ,and the trichomes still look clear.I know there supposed to turn yellow ,but should they be that yellow???WHEN WILL THEY BE DONE?there takin forever any help would be great!thanks everyone.

those look great! it does look like at one point it got a fert burn (tips of leaves) just keep an eye on the trichs and the pistils for maturity

It looks like nute burn on the leaves. What is your feeding schedule like? What nutes do you use? pH?

yeah ,they definitly got burned ,my ppm got a little high rite before i started striaght water 4 days ago,thanks for help.
