How long do I flower my plant ? First timer.

First time grower here.I started flowering my plant about a week ago. How long should I flower it until harvesting. It's currently about 48" tall I am guessing it'll take around 8 weeks but want a professional oppinion it looks amazing ,But I also wanna know if theres anything I can do, to increase my yield/potency on a budget . Thanks for the advice in advance .

keep track of time and post pics as you get closer to harvest.
people can try and help you out based on looks.

thanks bro,Will do ,Im kinda skeptical of sending pictures though ...

Yea I'm the same way with pics cuz all I have are on a phone which I keep locked tighter than a frogs ass but you need a 30X magnifying glass and keep an eye on the tri's when they start turning amber harvest but I try to harvest as soon as the balls fill and start turning a milky or whitish color... Lots of info just like said ablove keep an eye on the days...
