When to add nutes for "final two weeks"

Okay this seems like it should be an obvious answer, but it's not so please read the full question.

Updated: Maybe a better way to ask this question is: Should I add advanced nutrients overdrive before or during my flush?

I have a bottle of nutes (Overdrive from Advanced) that says to add it during the last two weeks of flower. This initially seems obvious, if you flower for 10 weeks then you add it during weeks 9 and 10, simple. However what I'm confused by is that if I'm flushing for the last 3-4 weeks of flower with nothing but clean water does that mean I should be adding these nutes durring weeks 6 & 7 (the last two weeks of flower that I add nutes) and flushing weeks 8,9,10 with clean water, or do you add these nutes during the last two weeks of flush?

You aren't gonna be happy with all the different answers you are gonna get on this.

I feel a flushing argument coming

Here is one .... Last two weeks ( water only )


Next ...

I wasn't trying to start a debate one when/how long to flush, just wondering if I should add the overdrive before or during my flush because it says to use it for the last two weeks and many growers are flushing the last two+ weeks which makes it seem like it's intended to be used during flushing.

Well i suppose if you added it during a flush, it wouldn't be a flush now would it.

Many others don't flush at all and just feed low strength nutes(or reg dose) at end of 2 weeks then harvest. They say their smoke is fire without flushing...
At the end of the day its all up to you

On a 10 weeker you use it on the weeks 8 and 9 together with base nutes. week 10 flush only water..depending of your strain how strong EC remains constant and plants look happy...meaning if you EC before like on week 7 has remained 1.8 and not going up or down then that is the strength
you will aim for , so first empty tanks ,fill fresh water and add 2ml/liter Overdrive check your EC and add basic nutes until EC is on the desired value..(if EC still was a bit low you carefully use A BIT regular PK 13/14..but be careful with that mix) I am in the process of testing Overdrive my self too at the moment...PK products are a Hell stronger plant killers than Overdrive so with them you need to know how your strain handels things..
This is for nutrient reservoir users...the hand watering or dirt growers might be different..

So sorry you have a ten weeker
