I did three out of four plants and this is the only one that has happened to

Hi @shag Welcome to GN. That plant does not look happy! More importantly you need to look at reducing your pH as soon as you can so you dont get nutrient lockout for your other plants. Your ppm is looking fine, but something is not right. Best to fill out a support ticket so we can have more details:

Is your ph pen still broke?
Could be lockout.
Do you have an air gap between the bottom of your net pot and top or your nutrients

I had got a new ph meter
I got 3.5 gallons of water with net pot 1.5 to 2in from water.

To I cut all of hanging dry leave with complete defoliation from yesterday to today some leaves started sticking back up the ph 5.8 and ppm 950-1050

I’d go ahead and switch if you want to. Maybe just straight water once in between the switch.

I didn’t read back far enough and realize you were in Hydro. I would just take regular water that has been left out for at least 24 hours if it’s city water and just basically give it a rinse. Unless you have a massive amount of ro water laying around you could use.
And just fill your system and let it run for an hour or so just to rinse the old nutrients out of the roots. Then just dump that and put in your nutrient solution and let it go.
This way you won’t get cross-contamination of nutrients from one nutrient system to another.
