You could also transplant, since you’re not in flower & not an auto.
This is crazy!
What kind of water are you using, bottled, r/o, distilled, tap?
I’m using tap and the lower ph I put in the higher it came out
Well, then something is off here. What soil do you use and are you using plain Ph Down?
It’s a store bought compost potting mix of some sort.
It must have a lot of buffering in it if the Ph won’t come down. Must be loaded with lime.

But what I don’t understand is that all 3 plants are in the same soil.
Ok, that’s even stranger. I have to say I’m stumped.
Now there is one thing I use apple cider vinegar to ph down but there again I used it in all 3 plants
Hmmm, maybe there’s a bacterial issue? Maybe the compost wasn’t broken enough, so there’s a lot of nitrifying bacteria still in there? That one plant might be more sensitive than the others? I’m just grasping here.
I’ll buy that.
This plant looks just fine.

Are you sure your Ph meter is working properly?

Maybe not. I kept checking it against the clean water I ph downed and it moved to the appropriate reading then back in the run off and it would shoot back up in the high 7’s. I will pick up some test strips and see.

Looks like heat stress for the lighter discoloration and tacoing.
When your ph out is higher than ph in you have a toxicity. Flushing with ph of 5.5 should have fixed it but if not I would try recharge. I have had to do this by flushing with about 2 gallons of recharge and it got my ph down cause it helps with ph lockout. Hope this helps
What is recharge?
