Can anyone help with waxy leaves and some yellowing?

Posted this in the wrong area yesterday.

I didn't make it home in time to catch a picture right before lights-on, but I can pull that one out of the room for a pic if I need to.



I just got my temps from scorching high 90s down to 70-80 steady.


Most of the ladies look great, one has yellowing leaves and shiny dark green leaves(they almost seem waxy, and have some downward claw action.) at the same time, another has some yellowing. I'm still seeing a lot of stem between bud sites on the colas, is this too early for this kind of yellowing?

Looks like some nitrogen toxicity going on.

That was my first guess, but I haven't added any to the feeds. I'm using Jungle Juice, which does have some N included at all stages, I'll try to tone it down with that part - I think it's the micro. A few of them have gone thru some issues at one point or another, and they just bounce back stronger! It's starting to stink out there!
