It's been 4 and 3 days in suppose to be a 6 week flowering plant I was going to leave it till the 31st but your saying on like the 7 of August Sent from my iPhone using Tapatalk
Yeah it definitely needs to fatten up still. I wouldn't focus on the weeks so much. If you get a cheap jeweler's loupe you can inspect the trichomes up close. That's how you'll tell if it's truly ready.
Not a pro for sure, but when I zoomed in on your picture, I think I see a few amber trichs! It maybe the lighting, but if they are amber..harvest is not far away..)maybe less than a week, depending on strain, environment, etc) You need a Loupe, Telephoto/macro lens, or a cheapo smart camera microscope (under $15 at Amazon)..Then, decide what high you are after..Note: drying and curing provides at least 50% of your bud's quality.

Once all your hairs brown out and shrink/recede start checking the trichromes, your buds still need to swell/plump your looking at weeks
