m0useanswered grow question 3 years ago How old is this plant? diary says week 6, if so it has a bit of time to bulk up but you wont be getting much out of it in the end I think.
The buds do not look good. even with early stress it should have something better then this.
Your early stress of topping is nothing new, I have seen topped autos and seen bigger yields before, I have also accidentally snapped branches with topping and they did well.
The one week said you supper cropped the plant, supper cropping is the process of bending the canopy to the same height but I did not see this reflected in your photos?
Might want to look at your environment and see if that playing a role in this outcome.
The seeds genetics may also have been wack. No idea where they came from diary is custom breeder and strain.
If it was bag seed or from a cheep site/bank this might be you get what you pay for. Then again autos are all over the board in terms of how they react to different stresses.
Good Luck!
