yellow during flower

[blink_inc]

Just wondering how much yellowing is normal during flower.
Some (most) of the ScrOg undergrowth is yellowing and dying however the tops seem nice and healthy.

Am I short on N?

Can it hurt during flower, to add veg nutes. ie Botanicare pure blend.

Any feedback?

its all good dont worry some strains yellow more than others my cronics turned nearly all yellow in the last 4 weeks of flowering but my n.y.c.d. stayed nice and green:thumbsup:

Happens to most screen grows- the stuff down below that's not getting a whole lotta light/air movement gets cannibalized for growth up top.

thought so. I just didn't want to confuse it for a lack of N orPH lockout.
Cheers.
