Dude, from my readings here at RIU, there are 2 ways to know when to harvest, checking trichrome with a scope or the Color of hairs (pistils) , more red brown hairs or trichromes will give you more stoned body high, less red brown hairs or trichromes will give u head high, so in your case i can't tell because you took the picture under the HPS, which makes it hard to see the Color of the hairs , take another pic with a flash or white CFL , while the HPS is off, i am in my second grow now (my first totally sucked) , today i finished 7 weeks of flowering tomorrow is start of week 8, check the pics they are last weeks (7th Dec) when i finished the 6th week, i guess i'll keep them another week or two cuz i wan't them to get bigger, i grew three, only one was a female
, if any experts can advise i'll appreciate it , cheers
