Yellowing new growth!?
New growth is yellowing is this nitrogen deficiency? And it’s only happening to this strain. Also growth in general has slowed. Temps. Have been getting down to about 66-67F Bc of the cold front that came through.

Rapid yellowing of some leaves
I've noticed strong yellowing of some leaves overnight. It usually happens to the lower leaves, but in my case the whole plant is pretty flat, so there's no real distinction between lower and upper leaves. Is that just flowers taking up nutes from lower leaves or some deficiency?

MicroScrogger
I'm starting to notice yellowing of leaves almost daily now on a Critical XXL scrog grow. She is 5 weeks into flower, had a rough (cold) start, and has always been a bit stunted. I was worried I'd overfed (3ml / l biogrow) so scaled back for 2 weeks. Is this normal?
