What are the phases of flowering

I know this probably depends on so many factors but I was wondering if anyone had any guidelines on the phases/stages of flowering. I'm asking because I'm about 40 days into flowering and today I noticed many leaves are turing yellow. So I checked a few threads and many seem to indicate it's normal. I've got less than 10% red/brown hairs and I'm hoping someone can give me an idea of what I should expect next, how close I might be to harvest etc.

Again I know it all depends on the plant, the strain, the light, the nutes etc.

Any thoughts? I guess I'd rather know that continue to ride this rollercoaster.

the leaves are turning yellow because the plant is using up its nitrogen and your bloom fertilizer has little nitrogen in it. it is a perfectly normal growth pattern.

it reallly is impossible to tell harvest time - the range would be 2 to 6 more weeks depending on strain and conditions

we want pictures

I look for new leaves, baby leaves growing from the heart of the buds, and I look for "the hairs" (stamens) to start turning color. It is natural for a few of the other leaves, the larger shade leaves especially, to dry up, die, wither, or turn yellow.
After I see some hairs turning red or brown, it is microscope time! Over the eyars, ive added an extra week to the FLOWERING STAGE ad I get more weight and more larger buds and I get a stronger "COUCH LOCK" HIGH TOO. I also get little wierd fingerling buds, almost white, that grow out of the big buds too , by growing an extra week.

Here are a few pictures of the buds (I know not massive but it's what I got) a leaf (the light throws off the color and the whote deal.

I don't want to couchlock effect. In fact the opposite. Honestly, I'm just excited as hell to be growing buds.

Anymore info is apperciated. Great to have a place like this to figure shit out.

is it just the tips ur talking about? they look burnt

You really ought to take a picture in another light so we can see the actual color of the plant...right now, all I can guess is that based on picture 3, your plant is rusting.

Well, at least you don't have a Fe(OH)3 deficiency.

Seriously, though...DesertRat's right on the money.
