Yep I’m just using flora nova bloom originally I was using the 3 part flora series at 1/4 strength but idk no matter what I tried I feel like my plants don’t really like it or I’m not doing something right so I figured I’d try the one part at 8mL/G
This is a good thing actually, you recognize that your plant is telling you its not happy.
Just remember, only try a single remedy at a time and give it time to show a reaction.
Might be worth it to check the roots on one of them, I'd look at the one that's lime green, just to rule out root issues. Like if they are slimy or small rootball, could be indicators.
I had my girls get cold roots only one night and they went from pic 1 to pic 2.
This progressed over 3-4 days, after much reading and asking, I diagnosed as P deficiency due to N lockout from cold roots.
I'm using a different grow, in Miracle-Gro moisture control, feeding 24-8-16 plant food at half strength every 2 weeks, otherwise tap water ( PH ~7.0 / 200ppm). The fix for my girls was to give them a feed of high P.
Sucks but dealt with it, they are bouncing back, took 3 weeks. I now keep a heat mat under them at 68F/20C.

Not saying that this is your issue, just sharing my experience.
Good Luck!
