Plants aren't doing good.

They don't look too bad. You can recover them.

I have the same issue with my tap water. It takes a lot of ph down to defeat the buffers in the tap water.

I mix 15 gallons at time at least 24 hours before I need it. I may have to adjust the ph two or three times but it eventually stabilizes. Don't be afraid to take it to 5.0 on your first adjustment.

I get a 10 liter watering can, add 10 liters of water out of the bath tap. Let it sit for 24 hours to get rid of the Chlorine. Add my nutes and then add PH down. I get a reading of about 5.8 - 6.0 PH and then let it sit in the watering can for another few hours and check the PH again. And it's back to 7.0 - 8.0
Stop waiting after preparing. Prep, check, feed. Discard any excess or use outside or something.

I've made up 10 liters of water so I am going to add some PH down until I reach 5.0 and see how I go from there. Thank you for the help :)

I wouldn’t even let it sit trying to get rid of chlorine because it’s got chloramine in it too and it’s not going anywhere. Just use it straight out of the tap.
I just set the PH to 5.2 and I'm going to see how far it rises in the next few hours, this is the second time PH'ing it :)

I think the main problem is the tap water is very alkaline and it has these kind of alkaline buffers in the water that cause it to rise back to it's original PH. But I'm going to keep testing until I find a solution :)

Ph Issues are also why coco is normally DTW (drain to waste) with at least 10% by volume runoff. When nutrient solution is applied shortly after mixing the "Ph drift" you speak of happens in the planting medium allowing the plant to uptake nutrients through a range of Ph levels. Then, when you feed her again to 10% runoff you basically reset the system and your plant runs the drift again. The only difference between what you're seeing in your resting solution and if it were immediately applied is what the plant uses.

If you insist on letting the water sit to 'evaporate' the chlorine, why are you adding nutrients and adjusting at the front of the process and not the end.

I draw my water a few days in advance (not for chlorine reasons)...and I add nutrients at the end. The very very last thing before watering is the pH adjustment. Moments before pouring into the pots, don't adjust then let it sit around, you only have to re-do it when you use it.

Oh. I do add the nutes at the end of the process. Then I PH the water to 5.8 and let it sit for a few more hours and it rises back to 7.0

I think I get it now. I don't need to let it sink around for hours. I just need to PH it and feed them. I just needed that confirmation :bigjoint:

This could be your hiccup. I only ever rest my solutions for about 15 minutes to ensure even distribution.
For sure man, I let it sit for ages and keep doing tests on the water like a mad scientist. I even wear gloves and masks when I am messing around with the PH and stuff lol I guess that is my main problem, I just need to PH it and feed them ha ha :bigjoint:
