Erm not too sure this plant does look like its still got a long way to go so Im pretty sure the buds will double triple in size in the last few weeks though I not too familiar with auto flowers I don't grow them I have once but I thought the idea of autos was to save time and to me they take longer than a photoperiod clone so whats the point lol though best of luck im sure she will still yield well the most powerful tool we have as growers is patience :) are you following your nutrient feed table ? could be a reason too if the balance isnt right she wont grow optimally :)
