I’ve got a Pineapple Express auto that’s on day 43 and I was noticing it looks like the stems (and leafs) are turning light lime green 
Not really yellow, but not the typical green either… Its got me a bit puzzled …
Normal for that strain or do I have an issue ?
Are you talking about new growth or old?

Here’s an example of what I’m talking about:
Just seems a lighter shade of green then what my brain is used to seeing with branches I guess… 
All indication is the plant is fine aside from that …
May also be that she needs a little CalMag … I’ve not fed any of that this cycle (which normally I do)
I think thats just from her stretch in early flower to be honest.
Im sure a lil cal mag wouldnt hurt but if you’re not seeing anything else to back up that suspicion like on the leaves etc then i wouldnt be too worried
Nah that’s pretty well all … Not as far along on Day 44 as other autos I’ve ran, but as we all know autos do what they want…
Like my FastBuds seem to be a lot quicker then these Barney’s… So it goes I guess… It’s not a race 
I’ll give’em a round of CalMag next watering just for good measure.
Best of luck with the grow
