Final Flush, Clearx, or Plain Water for DWC?

I'm nearing the end of my first grow and after reading many threads, I still haven't found a consensus on how to finish my grow. I use DWC bubblers and am still at least a few weeks away from harvest.

Do I just give the plants a final two weeks of plain water? What about keeping the Sweet Leaf and/or Hygrozyme in there with the water while flushing?

Is it worthwhile to use clearx or final flush? If I do, then how long go I flush after that?

How do I know when it is time to begin the flush? What are the signs to look for?

Thanks for your input!

You should use at least a 60 power microscope to examine the trichomes.

When you find the trichs are mostly amber and red it is time to flush.

You should have already have reduced the nute load
from a max at week 5 0r 9 depending on the strain.

By week 8 or 12
you should be down to about 25-30% load
until the trichs mature.

Then start flush with clearex.

Follow the directions for hydro on the label.

I flush with RO and clearex,
until the leaves start to turn yellow from lack of Nitrogen.

I don't adjust the pH,
since there is no reason to.

I have run RO only for up to 6 weeks.
This was the result.


This was White Widow.

Thanks Earl! Informative as always!

Anyone else have input?

Do what he says. No other input is needed.

trichromes should be turning milky white to amber under microscope at peak harvest.
