Week 4 flower - N deficiency?

Ok week 4 and things aren't look so hot. I am using BMO nutes. I tried to taper off the veg formula the first couple weeks into flowering, but now it looks like they didn't get enough N possibly? I feed once a week according to the bottle, so I'm fairly sure it's not nute burn.

PH run off is 6.8-7 every time. Nutes are PH adjusted to same range, so I'm 99% sure it's not a PH issue either.

if you sure about you ph...i would guess its N deficien...this is normal in this fase where you take out the N to add more Phos...to stimulate flower ....add up little bit you N and see what is gonna happen...this is my guess, anyways

yeah, u cut the veg too early. you can give em 1/4 -1/2 strength veg nutes for next 2 weeks or so- I do also notice the start of a P deficiency noted by some of the lower fans that have turned bronze and whose tps are doing 'the P twist'. maybe want to up ur bllom ferts a tad as well

just not too much. u want to control the yellowing at this point until final 2 weeks before harvest. otherwise they look good and no other signs of issues that I can see. yellowing is normal towarss the ends so no panic, just next time keep em on the veg until week 3 or 4. alot of growers continue with the veg at half strength and start with bloom half strength first or second week of flower. looking good and u should get some quallity smoke. I would guess little over half zip combined.
