thanx Honkeycorn for the pics! i just cant quite tell which def. i have im thinking it might be N because i have those dark green leaves and they lighten up as you get closer to the buds
looks like something was chomping on one of your leaves
Dont forget some def`s resemble each other, getting a lil lighter towards the bud sites is normal though. Newer growth is always lighter until it mature`s.
yellowing is either due to lockout, lack of nitrogen or magnesium def usually. I'm not a pro at outdoors but those ladies don't look too bad to me. Ur soils ph will have alot to do with it too. And being that your outside you def wanna keep an eye out for bugs especially those little fuckers...spidermites
I don't see a def because it'd appear in the older leaves first. I just see that's time to rise a tad the ppms IMO..it's a common thing (for me) in pre-budding to have some slight yellowing in the newest leaves surrounding buds and when that happens I just switch to full strength nutes. I currently have a patch exactly at week 3 and they all did this.
