Did it get stunted or held back in veg?
I've been told (by somebody that doesn't really do autos but has been growing for longer than I've been alive) that stunted autos often end up being a main cola and not much else.
I know where I went wrong with these ones anyway.....I'm crap at hand watering and they got way too dry early on.
The ones in the background are photo period plants that ran out of water. The other autos I managed to stunt got topped by slugs so they looked a bit different and ended up even smaller but I still got the best part of an ounce of nice smoke from one of them.
I may have stunted her in veg, not sure. I do like to let the plants dry out a bit between waterings, but I don't think she got as dry as my photos would have. She is 27 days above ground and today measuring 7 inches tall. Is that short for an auto of this age? I have no idea, this is the first auto I have not killed as a seedling.
