These plants will certainly make it if you get the problem under control.

If the temperatures are as u said at plant level the light is probably not the problem.
pH is a bit low for soil but they dont show signs of that being a problem either but they do look overwatered for sure.
Are the pots drained? If not fix that.
In soil water well, let dry and water again. Be very careful with nutes so far but I can't say that they look overnuted so my guess is that it is most likelly the watering schedule that is the problem here.
It's easy to overdo the care.

Good luck.
