I was growing Purple Punch auto before. And other purpled pheno in some seeds. They are showing purpled bud later stage.
This times is my 2nd round purple punch and is this purple from phenotype? Or could be sorta problem.
Pot : solo cup pot size.
Medium : soil mix perlite with little slow release sub nutrient.
Training : Bonsai my plant, defoliation and mainline lollipop.
Feed : watering with pH water. Runoff seem high at 1000ppm.
5weeks from sprout and first calyx at sub nodes change color
That’s normal Growie, not every plant will express colors even from the same seed batch 
These are two Purple Bubba Kush. Both were grown exactly the same but each express different phenos (traits).
It’s unfortunate that unstable genetics are kind of the norm in cannabis.
Imagine driving by a corn or soybean field and seeing this kind of diversity.
Or even planting a packet of vegie seeds in the garden and seeing so much variance.
I realize that’s a bit of an unfair comparison, but it speaks to a point I think.
It’s frustrating and yet exciting to see what comes next, all at the same time.
Agree, I’ve seen more and more of this over the last year or so. I think they’re selling F2s when you get so many different expressions from the same seed batch. I could be wrong just my humble opinion
Thanks !
And thanks everyone .this is my first time get not green color, typically they only purpled at tips on cola buds like this
buds are forming and start changing color too . So excited
Looking good Grow Bro….well done and keep doing what you’re doing. I’ll occasionally get one or 2 with some color
Gorgeous! I have played with 15-20* climate changes, and PH swings. I always got my best colors in winter and on plants I was flushing at the end. A 2 week flush w straight water will bring out all kinds of colors.
Are you in Northern California? Just wondering about the amounts of climate changes. I send mine
