Do you wait till the hair start dying off to give the final feed? and is it full strength?

Actually, what I prefer to do is taper off, and end up with only a very small amount of molasses or malted barley extract in the last week or so (molasses would be around 1T/5gals water, MBE is much less because it's so much denser). I want to achieve a nice yellowing by the time they're ready, because I personally prefer a more blonde-colored product over a deeper green product. Just a personal preference, I don't know why I like it like that, but I do. I can't offer any other reason outside personal preference.
I have done things both ways, and I haven't found yield to be sacrificed, either. What I did find when pushing feed a lot harder (chem salt-based) that I could end up with some fairly harsh-smoking bud that tended to crackle and pop. Again, I cannot explain the observations, only that I have made these observations based on my own experience and mistakes.

First i want to say thanks for every ones replies the info is much appreciated!
hup234 so the plants will stop drinking as much and that is the time to stop feed? or water?
supermanlives i feed once a week, if your doing this how much do you tapper by? say its a 12 week strain from week 10 will only be water (this is the gernearl feeling i get from the replies in the thread) but when do you star to taper feeding? week7? and do you cut in half at every feeding after or 1/3 or what? by how much?

I'm with Homebrewer on this one and feed till end. Curing should get rid of most harshness and black ash, etc... Wouldn't starving also stress plants and affect yield? Funny though even Dyna-Gro says to taper and flush during last 2 weeks. I do res changes 1x/week, especially in later veg and flower to help prevent buildup of salts, etc... Crops are also a nice long 3 months from clone and 4 months from seed (12 plant limit, working on 24). Am I actually flushing up to 16X per grow cycle? I hear so much about having to flush being a myth. Whatever floats your boat.

Take this for what it's worth, as it was my observation in MY flower room...
I did a side/side with a Gorilla Grape cut, one being fed 'til the end and one given tap water for 2 weeks and neither out yielded the other BUT the one fed to the end got tip burn.
I tried the tapering down routine but things were still too green come harvest time.
Unscientific I know, and opens lots of room for debate but that was my experience. So I just start plain un-ph'd tap water 2 weeks prior to harvest.
Oh, my medium is coco

I got some plants that the big fan leaves have died and the hairs are 30% brown, 5% dead, is this the stage where i should start feeding water only? I only get the chance to go to the girls once a week so if i feed only water for 2 weeks that would mean they would or had a 3 week flush.
Are the 3 blade leaves going to die of too? I think the tree also pulls nutes from the leaves so is this the last stage of flowering? the yellowing of the 3blade leaves?

I keep a 65g res for my water/nutes. In mid flower they are usually drinking around 15 gal per day give or take. Starting at 10 days left to harvest, I top off my res with plain water. This slowly starts diluting the nute mix. Usually by 4-5 days left the mixture is around 25% or so strength. At this time I will use use up the rest out of the res, and at about 3 days left I will hit them with only plain water for one last watering. They are mostly dry by harvest but still a little moist.
I used to stop watering 7 days prior to before harvest helping me dry faster. Well, it was but then I realized it was better to do a slow dry, so I started watering up to the third day before harvest. Come harvest they are a tad moist instead of all dried out in the pots. This added another day to my drying. (which for me was a good thing)

Bottom up yellowing, or an overall fading? If they're in the ground, I wouldn't worry too much about flushing, it's pretty hard to flush the earth. I don't concern myself with the percent of pistils that are done vs new, but an overall appearance.
Whether or not the confusion leaves will die soon is partly a matter of their location. If they're high up on the plant, chances are they'll stay green for a while.

HI SeaMaiden its all the big fan leaves that have died off. they are in pots 5gall buckets and DIY smart pots all between 5-10 Galls sizes. recently the wind blow over one and i found the top 5 in of soil wet and under that bone dry, so i checked all or them and sure enough all are bone dry to the bottom. each plant gets 3/4 liter a week. it rains about once a week to,(going into dry season) some are 6 feet some are 3 feet. i need to get some pics though.
The leaves are/were yellowing from the bottom up! i am not familiar with the term "confusion leaves" did you mean the 3 blade leaves that are now dominating the plants?
Truth is i never grown indica crosses that are so big these babies have put on some weight and i don't know when they will be ready, if these were the Jamaican i am accustom to growing i would have pulled them already from the looks, but from the time they would have only been half way, i don't believe plants can finish so quickly! i cant weight to get to the F3s!
Can you post some pics of plant that are ready for flush?

Hi baja, yes, I meant the 3-lobed leaves, I call them confusion leaves because they're a result of hormonal confusion.
If all the big fans have died off, I'm thinking it's close to done, especially if they've been in 5gal buckets. I've observed that pretty much anything put into a smaller container tends to begin and finish flowering earlier than those that have more root space.
Can you loupe the trichomes at all? I don't flush, but I do need to get pix up of my girls and I've got two that are in that late-flower fade mode right now. Those will have to come a little later, though, I haven't yet had my first cup of coffee and that's a requirement.
Oh! Before I forget, I'd like to give a little list of stuff I look for/at when trying to figure out if a girl's done or if she needs more time.
* Trichomes are only part of the picture for me here, but generally I'm looking for cloudy trichomes over mostly clear or mostly amber.
* Pistils, when they're still throwing lots of new, fat white pistils, even if there are lots of others that have died and gone red, I tend to let them go a bit until the new pistil growth slows or stops. Kind of like how I do popcorn.
* Vegetative growth appearance, is it still dark green (this is feed dependent, of course), or are we observing what could be described as fall colors?
* Bud growth and development. This is where it can get just as tricky as gauging by trichomes, because if you're looking at your plants closely every day it can be difficult to say whether or not they're still growing. Anyway, if those buds are still packing on size, girth, weight, they've got to be allowed to develop if possible. Missing harvest by a few days on the backside isn't such a big deal, IMO, so I think it's better to let them go if at all possible.
Now... I just noticed that you said these 3-lobed leaves are dominating the plant, and in my world that is not a good thing, it indicates the plant is no longer in reproductive (flowering) mode, it's gone into vegetative mode. And if that's the case, I would yank her ASAP.

She doesent look like she is in veg but she does look like she is getting leafier. i will rip soon.
there is some science regarding the plant's exchange of nutrients when uptaking sugars.
a lot of growers are happy with spiking molasses or any nutrient company brand of sweetener carb towards the end or during flush.
I personally find running carbs at the end produces a nicer product
