My first attempt at DWC failed.

Jumping in with both feet. Read everything I could find. But I started before I was ready. I didn't know that you don't use organics in the water.

I also used tap water that was ran through a carbon filter first. I had to use a lot of PH down to bring it down and it would climb every day.

The water turned brown and stunk like sewage. My roots were brown and gooie. My baby hat turned a bright yellow no matter what I tried.

So I started over. This time I used RO water and Masterblend. I put 10 gallons of RO in a tub and mixed in Masterblend and the PH was perfect.

Only time will tell if she lives. I did trim off the dead roots and I put a dropper to feed the nutrient water from the top until new roots develop.

First photo is before and second is after. She's getting her color back and is growing again.

good luck!

Yes run sterile, for sure until you get that dialled in - I'm not planning on changing from sterile any time soon, as it intrduces too many new variables to try and understand and difficult to measure, in my opinion.

- also water temperature - it needs to stay low enough to discourage any growth in the water but not so cold it affects the roots, about 18-20c is what you should aim for.

Also how much water capacity is in your system - more volume of water should result in more stable PH levels.

Unless your tap water is super hard or high ppm dirty it probably isn't the issue. I would blame the organics.
After playing with dirt for a few years I am back to where my heart is - full hydro.
I use filtered tap water in my grow (less than 100ppm).
Buckets on the left don't even have air stones in them. They are Kratky buckets that I added a watering system to so they maintain a lower level of water after the plants initially drank them down. ✌
