How many days do you think I have left to harvest?

Weeks my friend. You are just leaving the first stages of flowering and have a long way to go from the looks of it, much more weight is needed to be gained. Side Note: have you started addressing the issues you are having with over feeding yet? A flush and correction may be in order, I will follow your grow to see ya progress, best of luck brother and feel free to reach out.

Hey brother. Well after looking through your diary, I'd just be repeating what they said. But then I looked at your seeds guidelines. And there is no diary to go from. It might be is genes y its looking future away than its actually done. It states 49-56 days. And you are about 5 weeks in right. So by the guidelines of the strain its saying min7 max 8 weeks. At looking it looks like it has 4-6 weeks but you really are in uncharted waters. To get a good judge of how them genetics mature id look through similar genes from the same breeder. More often than not, you'll find many strains near the same way they grow. Some get frosty earlier on, some look like yours. You might be surprised and she stack up in the next 3 weeks and when it hits around that stage you should ask the question again. You are looking for bud of course, but the pitils, (white hairs) you want Amber and them curling back into the bud that will fill out them spaces in the next few weeks. Looks like she's coming out of pre-flower but again, you really need to look at the genes of similar strains from that breeder. As everything else is just a guess. 80-90% cloudy and you can hang dry whole and dry for 6-10 days at 50-60 RH 19-21C temp and in as dark a place as you have and she'll finish up nicely, or you can wait and let it go 100% cloudy, all depends how you like your smoke, more clear when you dry will give you a more sativa high and a more cooked lady leans more on the indica side. Usually tent is fine, just have good air flow not air blowing directly on the plant now. Good luck pal.

I agree with @GrowingGrannie and @Spuwuky ,,4-6 weeks "

Judging by your journal, probably about 5 weeks, give or take a week based on genetics. You have a ways to go.

Your trichomes are all still clear, you leaves haven't started to change color... you've got a long way to go yet - 4-5 weeks? If you have a microscope or a loupe, check the trichomes to see when they start to turn amber.... you'll want to see about 30% amber when you harvest. Good luck!
