I am thinking about moving her from this 4l pot to a 11l pot. I know i can't change the pot during the flowering, but there is a correct timing to do that? Is now the right time? She is an autoflower with 22 days of life, thanks!
When it comes to transplanting what I always advise is to get her in her largest pot as soon as you can that way she will have so much more room to develop a huge root system allowing your plant to grow taller or produce fatter buds yes it will stress them but rather get that out the way sooner then you can better train your plants knowing you dont haveto transplant again though this is your plant my friend you do what the hell you want :)
