What do you consider day 1 of flowering ?

I know this is post is just over a month old but I have this same question and am still struggling with the answers.

I know the plant will tell me when it is ready but by that time it is too late to flush. If the 12/12 switch is the start of flowering then I am due to start my flush in a few days instead of a week and a few days.

Also, I have a pure sativa that took 3 weeks after the 12/12 switch to show pistols. I have started the flowering nutrients from the first signs of pistols instead of the 12/12 switch. The plant has a 90 day flowering period, does this 3 weeks count as flowering?

So, should I start my week 1 of flowering nutrients from day 1 of 12/12? And should I count the estimated finish time from 12/12 switch to accommodate the correct time of flush at the end before harvest. Or is this also played by eye? I am seeing the start of browning pistols on the buds which have just started to turn brown in the past 2 days.

This is all so confusing, someone must have some concrete evidence suggesting the correct start date for flowering by now surely? I have every date noted for each stage of every plant for this grow. I can return with some of my findings for what my finish date works compared to the breeders estimate if anyone would like me to report back?

No. The plants still need a lot of Nitrogen through the first 2-3 weeks of 12/12 during its stretch period. I typically add my flower nutrients into the mix at week 2.5.

Don't flush. Problem solved.

Did you ask the breeder? They are the source of the confusion right? Most are pretty good about Q and A’s. It’s never going to be that concrete though. If we are talking seeds, how long you veg is going to really effect when the initiation starts after 12/12 begins. If you start 12/12 from seed, it’s going to take weeks and weeks to initiate flowering. If you veg until the growth is fully mature, all the leaves are alternate instead of opposite it will initiate flowering in days after the flip. If you’re talking sativa from seed then phenom difference can make a huge difference

As for flushing, I don’t do that but, The real question is what does a plant and buds that are two weeks from maturity look like? Posting pics here will get lots of input. But again with Sativas, it can get tricky. Those fuckers just keep pushing out new pistils forever. Here are some Killer A5 Haze day 77 from flip. To the left is the Malawi/Haze phenom to the right the NL/Haze phenom.

The vast majority of breeders use flip as the barometer. That is pertinent to know simply as a rough guide. Individual cultivars will inherently differ. Doesnt mean it's the best system, simply the most prevalent.

For example Americans talk in terms of pounds, feet and inches despite the imperial system being manifestly inferior to the metric system. But if you're in the US it is pointless to talk in kilos, cm and m because most dont understand it.

As always, trichs determine ripeness. Pick a standard and be consistent with it simply for your own consistency and comparability.
Why do we weigh in grams but then switch to ounces and pounds? I'm going to start the dekagram or hectogram sacs! Fuck an oz I want a hecto!

I count day one on the flip and assume most strains are 10 week min, same shit different pile. Early is a bonus but never really get that ever.

How do you count from in an outdoor scenario? How would one compare the flowering time of the same strain to its indoor clone?

According to Kevin Jodrey outside is from elongation. Its obviously not as uniform as 12/12 switch which most everyone else with a brain uses.
Elongation and 12/12 switch for most strains would be pretty close, 3 or 5 days difference, bugger all in the scheme of things.
Majority of breeders give indoor times but worked lines and quality breeders should also give out door time frames ( Mr Nice does for eg). A clone switches faster id argue and may save 4 to 5 days or more over a seed plant.

I feel that the obvious choice is to count from the beginning of flower formation since that’s the most distinct point for observation. This gives the most accurate representation of a plants biological flowering time. However that time will vary based on environment/grow conditions so usually it’s not important to count at all.
