The seed bank says it will finish in 80 to 90 days, I am currently on the 52nd day, the pistils are red, how will it last for another month?

Pistils aren't the best way to judge ripening. Pistils often can brown up as early as a month before the trichomes say it's ready. In your diary your pistils are dark but they really haven't shriveled up yet either and are still poking out. I could see it running another 2-3 weeks at least. Look at the trichomes and eliminate some of the guesswork.

Never believe the advertising.......trust your intuition.

It’s really hard to make that call with just a picture of the plant. It’s best to look at multiple things but most importantly is the colors of the trichomes. The consensus is to harvest when you see roughly 10-20% amber and the rest mostly cloudy. That is your best way to tell if it is ready to cut. The colors of the pistols also is a good sign as well. When nearly all the pistols are not white anymore then it’s usually close to harvest but your checking of the trichomes is always the best. As for what the breeder says, I never follow that to a T. It’s always a rough timeframe and I actually find that most of my plants go over the said time. In your case, in autoflowrs there are so many variables to it that make that timeframe nearly impossible to hit with every seed. So my sugggestion is to get a jewelers loop and check them trichomes. Hope this helps.

Your plant looks done right now, your diary name also says its an AUTO... Autos do whatever the fuck they want sometimes and this one seem to have entered early flower, im guessing this as their is no other weeks in your diary just the one on week 8 and the one pic. So from the lack of information this is my best guess giving what you have provided. In general suggested harvest times from the breeders are an average of what they found on their plants with how they grow them. Different style of growing and stresses will change that. I've seen some autos stay in veg for 7 weeks. and that alone is 49days. Don't think about it to much and enjoy the weed. Harvest and cure. Good Luck!
