Flush or not to flush, THAT is the question!

So I have my Foxfarm products (GB, BB and TB) in my grubby hands. I've read everything I can find on flushing but I'm still confused. I know I am supposed to use all 3 products together but I read conflicting things on flushing. Some say to flush every month to remove salts and other fert buildup. Some never never flush, that it stresses the plants. Other say flush 1 week before harvesting. I'm confused!

I'm just over 2 weeks in 12/12 and both of my girls have buds forming all over. I want to make sure I get the biggest buds possible. Should I flush them, let the soil dryout completely and then apply the FF products? Any help would be greatly appreciated!

The corect answer is: (flushing & leaching)
Leeching is done for a couple of reasons, first it can flush out excess salt and mineral buildup. Second is that it is useful for flushing out other organic waste products in the medium that are introduced by the roots and microrganisms. Third it can refresh stagnant voids in the medium(areas that are either wet or dry spots, or devoid of oxygen, deviant ph, etc).
Organic nutes are not as heavily derived from salts and thus that need is reduced however the other advantages still apply and perhaps more so since organic growing fosters a thriving herd of microorganisms in the medium, and ph flutuation is more common.

Pre Harvest Flush is usually cited as being necessary to use up or flush the mobile nutrients N,P,K,Mg and to restrict the immobile nutes resulting in a finished product with fewer chemicals resulting in a better quality smoke.

The key here is really not to create a difficiency of immobile or mobile nutes during the flush, thus the use of mollases, but instead to create a tapering off so that after 7-10 days the plant is right at the end of its resources for harvesting. Flushing too long and without supplying immobile nutrients can result in stunted finishin. Flushing is a good practice with both organic and chemy nutes. It takes practice to get the timing just right, and once again strains differ widely. If your plant is dark green at harvest you have probably not got it right, and if the leaves are all falling off you have probably gone too long.

In spite of the correct answer, the old addgae applies(atleast for me), if it ain't broke, don't fix it!

I leach my plant ever month. no matter what stage of growth. To remove build up's{salt/nut} let dry then continue to feed.

They gave you the right answer and now it's time for you to do the work

They can't do that for you

Like they said it depends on what your using and how your using it

You won't get it right the first time <-- NO MAGIC FORMULA
