Yes they are feminized and we have one growing on this plan so far going great the little gal.

I have space for a little and i have a 600W HPS so lighting not that bad...

The reason why im starting flowering at like day 25-30 is because i have only like 180cm in height of space... so ill branch em into smaller buds but with like 3-5 buds instead of one...

For the WW im looking for advice though and may even wait longer then 2-3 weeks before adding nutrients

Im running basic Biogrow 8-2-6 on the plants i have now.
And yes Biogrow is the name i plan on using their flowering nutrients as well.

Also this is something i find working on potplants is to take the fullsize out of lighting room for night as i have a completely dark chamber with 18-20C 24/7 which means they will get cold and dark at night and warm+light in day...
