Fairly typical for an outdoor auto.
I presume this strain is from Barneys Farm, so genetics should be quite well sorted, so this plant illustrates why autos are more suited for indoor growing with an extended lighting cycle and why trying to grow autos outdoors with sunlight is not that successful, as I have also discovered over many years and the sole reason I will never grow autos again, as for me, they have nothing to offer over what can be achieved with normal and more stable photoperiod plants, with their superior yields and ease of cultivation.
And yes, you guessed right, I am not a fan of autos at all!
Not much you can really do at this late stage but wait for maturity and enjoy whatever you are able to harvest.
