I'd guess 100g - 200g? if not dense, 75-100g... if dense, closer to upper limit...
they way time is measured with autos and when bloom starts is not consistent. if you've had those budlets (tufts of stigmas) for 2 weeks, i'd say you only have upto 10days more of vegetative growth left
(the remnants of vege growth as it switches to bloom mode, like the first 3+ weeks after flipping lights, the process still happens, but on an automated timer in the genetics of the autoflower plant - they still have to go through the same hormonal shift to bloom.)
you'' be able to guess better when vertical growth stops (vegetative growth = shoots and leaves). if it has stopped, without familiarity wiht density of the buds and colas produced, it's got to be a huge range of variance to have any integrity at this moment.
