Yeah most of mine were purple buds / purple leaves. Some of the seeds I have made had less purple leaves (like two phenos, REALLY purple leaves, or green leaves / purple nugs). But all have had purple buds, and at 7 weeks from sprout (3 weeks into flowering? they would start during week 4) the buds were clearly developing purple hues if they were the green pheno, and leaves were already getting lots of color of they were purple leaf pheno.
I wasn’t disappointed by the yield, it was one of my first autos, and despite hearing horror stories about low yields from autos, they did OK. Not the yield of a photo, but also half the time. The colors were what made me reverse and make some fem seeds though. First few were like 70g per plant, but I learned and got to 110g later.
Yours almost looks like a GG4 auto I got from Corey. They were BUSHES like that. And pretty killer smoke and yield, but no purple obviously.
Either way, your yield from autos with bushes like that shouldn’t be too bad… You might be pleasantly surprised. Won’t be the same as a photo, but wont take as long either LOL
Thanks 
and never really thought of giving auto’s a chance. They were just too small, same price per seed, finished faster but yield - just not there and when they first started becoming popular; auto’s were still inferior to photo plants in potency which made them even easier to brush off and ignore. But over time I’ve softened my opinion a bit, become totally infatuated with the spectacular beauty of many auto’s and their potency now rivals some of the best photo plants. Now, I find it very hard to NOT give auto’s a shot and realize that for me they’re not going to be an every grow thing, but like now, when the summer heat is warming up the hydro-tubs, auto’s have become an amazingly viable option to keep a grow going when the heat of a closed tent in the desert would and does become a serious issue for hydro (without a water chiller).
(a quick search will give you the back story, also you’ll see the TARDIS build) I did the original cross and 
OG is definitely the place to be. I was a member of RIU before finding this place and never looked back. OG is an actual community. Met a few folks here that became good friends in real life.
