You also have a mag Problem...put the Ladys in new, bigger shoes, with fresh soil.
PH from the Water should be at 6.5-6.8, Not deeper...keep on growing and dont watering too much or less! 🤙🏻
Plants look root bound which can seem like over watering or so I hear.
No need to give up at all they dont look that bad.
Ph your water from here on out and get some fabric pots, they are cheap and impossible to root bind.
You're plants look better overall but I'm struggling with maybe the same issue? Feel free to look at my diary. One recent advice mrpink gave was to adjust my pH so maybe? I wouldn't give up on your plants-- they look pretty good other than the wilting/drooping.
I plan to give my plants another day or so then maybe water with a more appropriate pH. My other theories are over- or under-watering, and/or heat stress.
