#3-how long do you flush before harvest in a dwc?
#4- do you cut all the nutes at the same time when you flush and feed only tap water?

1) DEFINITELY before the water softener.
2) I run the same nute mix from clone through mid flower, then drop everything in half and add MOAB for 1-2 weeks. Week 7 I drop the cal-nit entirely, and the last two weeks get plain tap water.
3) I don't know much about DWC, just DTW
4) Yup.

so the craziest this just happened twice!
I just replaced the res with the tap water and jacks the same way i have been by putting jacks with the epsom salt then waiting about 30 min until all those nutes are dissolved then adding the jacks cal nitrate. After about 10 min the water gets super cloudy and the ppms are getting considerably lower. My city tap water is ruffly 450 ppm at a ph of 7.2. I did a full res change twice same thing happened. This never happened with ro water? What am i doing wrong?

i havent even got to adjust the ph before it got cloudy. i just dumped some ph down in there to lower the ph of 7.7 (crazy) and the ppm just shot back up and some of the cloudyness went away?

So i decided to drain the res once again. I added my city tap water (not softened) to the system with zero nutes yet. My plan is to bring the res temp up to 68 (currently 58) and adjust the crazy high ph of 7.2 to 5.8 before adding any nutes. Ive added a ton of ph down, it almost seems wrong to add as much as i did but it only moved it a little. ive added 4 capfuls of ph down so far and i need more but im waiting a minute before i do.

You should pH after everything is in the rez and mixed well. The *final* pH should be 5.8.

The cloudy water thing? You shouldn't get cloudy anything as long as you don't allow concentrated nutrients to mix.

Cloudiness is caused by precipitation, and precipitation is caused by concentrated nutrients reacting with each other. The pH is mostly irrelevant when it comes to precipitation.

Update, i switched all the nutrients over to the advanced nutrients sensi line around the 3rd week of veg and I'm still having these same "rust spots". Im in my 3rd week of flower as well. I'm beyond stumped?

What is your EC and pH? Are you using RO or tap water?
