What's The Earliest Can You Use Overdrive?

I'm a new grower but I have 6 plants that have been flowering for 4wks now.It says on bottle of overdrive best when use in wk5&6 but can I use it earlier?

Well I'm guessing @ 3wks bcuz that's wat I did and its been 4 days and I'm seeing a lot of improvement already

Yes, you can always use Overdrive earlier.

Here's what the instructions on the AN site say:

Overdrive:

Use 2 mL per Liter during weeks 5 and 6 or the last 2 weeks of your flowering phase.

And honestly, you can use any nute early, if you want. It's always up to you...and your plants. If your plants are happy, that's really all that matters.
