How much longer? First grow :)

Hey guys! So these are my 3 flowering plants. They've been flowering for about 30 days now under a 400 watt hps. And some of the lower branches are starting to flop. The strains are gorilla glue, super glue, and master kush. I'm running fox farms soil and nutes . About 50% of the hairs are going brown. I know that doesn't have much to do with finish time. And I'm going to get a lens to see the trics soon. I was planning on doing 2 more weeks of cha ching then flushing. But how long does gg#4 usually flower and how does it look? Thanks again guys!

Got a ways to.go yet. Man.. I used to let my master kush go for about 80 days I'd say on average. Its all preferance though you could probably take the master at 65-70 if you like a more heady high.

Definitely let them go longer.
You can buy a scope cheap at a hydro shop.
