[Outdoor] "Where's Mary?"

Started an outdoor grow recently, no idea what I'm doing, it's all bagseed. Planted 4 plants originally and I'm down to 3 (1 male).

It's been about 4 months and it looks like they are coming into flower now, any idea how much longer I should wait? know how much bigger they will get?
My mate keeps telling me to harvest now haha.

Where are they?

long time to go dont harvest. they will get much thicker.

Not even close mate...you want the pistils (white hairs) to turn rusty and the buds to swell (not the only factor, but a good start) ...youre like 2-3 weeks in, 5-8 weeks to go depending on the strain...probably more like 8 weeks given the skinny, sativa like leaves....just my opinion...be patient and it will be worth it...you ever see white hairs in weed you buy? Just go by the look of it or buy a scope ...nice lil plant tho for your first time

Sweet, 5-8 weeks ain't too bad.
The plants are pretty far from where I am now, next time I go take a look at them, is there anything I need to do?
Prune, fert or something?

A lil high-p bat guano never hurts, or whatever you got.... just make sure its high-P and K....and i wouldn't prune anything that isnt ready to fall off anyways or is bug infested..dont want to stress her during flower...id say just feed em and keep em watered, theyll do all the work from here
