Looks burnt or magnesium deficient. I would change out the res to a lower EC.

its only 192 ppm should i still change it out?

Well then I'd have to say it's a deficiency. Damn man, my tapwater is harder than that. Does your TDS meter have an EC (microsiemens) scale to it? Get it to around .7 EC (700 microsiemens) and change out the res every 2 weeks.

It's easy to over-water a plant when TDS is so low.

I gotta say though, I have no idea how those plants got so big on 192 ppm. If you wanna run weak concentrations you just ned to change out the res often enough. I'm flooding in hydroton @ .8 EC, but I change the res every week.

userfriendly is right about the third pic, if your overwatering, the plant will "sweat" out excess water and cause the leaves to curl up on the edges like that
