Leaf curl, ph jump

Howdy folks,

One of the girls started showing signs of stress this morning. The older leaves have started to curl, and look off. Color is fine but leaves are funky. She is in a waterfarm under 600 watts, part of a 4 plant room, the other 3 are doing perfect.

Here is a pic:

I have loads of data so if there is specific info that will help figure things out, I probably have it.

I took samples of the water and the ph had jumped from 5.81 to 7.52 the first sample had some off white film, picture below:

Subsequent samples did not contain the film but I thought Id mention it.

Thanks in advance.

Res temp? You say pH swing - over what period of time?

I did a water change saturday night, solution was buffered to 5.81, this morning tested at 7.52 @ 71.3° f so call it a little under 4 days.

Im going to run samples of the other units once lights come back on in 4 hours.

Check your roots. pH swings can be an indication of root issues.

7.52 pH is not good. I would check your pH daily and find out how much it swings on a daily basis, not on a 4 day basis. Regardless you'll have to sort it out or you're going to experience issues. As hotrodharley suggested, I'd check your roots as well...you want nice bright white roots...anything less is an issue.
