To flush or......???

GreenGiggler, Here's how I see it: The leaves tell the whole story. Are they perky, perfect color, vibrating with energy? Then the nutes are fine.

I am very conservative with my nutes, and I feel out how much to use by looking closely at the leaves. And since I decrease my nutes each week after week 4 of flower, I don't need to flush my plants. I don't believe in completely depriving them at a crucial time, and my buds are never harsh. My nutes are really low, like seedling strength, at the end of my grow.

I'm doing a flush this weekend just to give them a breather, and I usually end on a 2 day flush.
 
You aren’t busting any myths. If you use full strength nutes till the end then you need to flush. If you lower the dose at mid to late flower it isn’t as nessassery. alltatup still does a two day flush at end. alltatup How much do you flush with on those two days?
 
@ Garret - Sorry, I was implying it would be cool if someone ran a lab test to dissect and test the molecule composition of a flushed bud versus a bud that had not been, as well as some of the other options such as reducing the notes with a shorter flush.

It would be super cool to understand the effects and differences that the different methods provide as and end result. (Least in my head it seems like it would be cool. The reference to myth busters was simply cause a commercial was on and they do that sorta thing. (Was not implying that flushing or not flushing is a myth, I am not settled in either camp as I don’t know enough yet).
 
alltatup. Ok cool. I don’t use any flushing agent. I “flush” with a larger quantity of water than when I feed or just water. TheGreenGiggler man I looked all over for test results. There are test being done on chemicals that were used on the cannabis, you would think there would be a similar test stating the say NPK levels pre cannabalisim and at harvest times for both the buds and the fan and sugar leaves.
 
TheGreenGiggler But. Lol if the nutrients are being leached from other parts of the plant, does the bud know exactly how much to take from the rest of the plant to finish its cycle? We cut that plants life short, so wouldn’t the plant have more stored nutes. And does the nutes in the bud get used up, can’t be completely. But idk.lol
 
And that research will come as cannabis becomes more and more widely accepted in our society. Then the grants to do the research will start flowing in; actually, they already are. Hemp and CBD research are huge right now.

And that's a good idea to flush with a larger quantity of water; my plants love a 48-hour flush now and then!!
 
As I mentioned above, there's still quite a bit of controversy--or at least disagreement--about whether it's needed or not. Ed Rosenthal notes that outdoor plants aren't flushed.
 
Garrett I look real closely at my leaves. I look to see what's going on with the older and lower leaves. If I see signs of too much nutrient, that's when I will flush them. Some folks recommend a 2 day flush every week, but it's just too much water lugging for me, so I don't do it that often.

Last week I was examining leaves and seeing a tiny bit of tip burn and some spots on older, lower leaves, so I decided to flush.

I can see that my leaves are really happy and perky today, the second day of their flush. I read (can't remember where, but it's in my notes) that the plants love the break and explode with growth after the flush, and you can see during the flush that they get happy.
