how long?

Hi I have a 23 inch purple haze plant thats outdoor. It already hase 21 bud spots where pistols show. Its been 10 days of flouering. How long wil it stil make new flouering spots? So it can start making bud growth. How many grams can I look at +- when I pic my food?

It continues to flower until it is cut. look up some info about the strain you are growing (google it) or go to the growfaq at the top of the forum page here on RIU and read all you can. If you can look up your strain, the info should give you a general idea about flowering time and possible yield. All in all, just READ.
