Curled leaves (PIC). Could pH change cause this?

So, this is a little strange. I just did a pH adjustment and topped off my aeroponics setup grow.

I noticed that just one of the plants had just 2 leaves that just kind of curled over themselves. (pic below). Any idea what could have caused this? The only thing I can think of is that the water I added was too cold or that I brought the pH down too low too fast?

I started with the pH of 6.4 in the res and adjusted it down to about 5.2 in one dose. Is that the problem? I just want to know so I can avoid doing that in the future.

The grow is about 3 weeks from seeds.

leaves are looking even worse, yet the other plants seem to be ok. anyone with any input?

New growth looks good right?! I would not worry about it as long as your new growth looks good.
Good luck mate!

twisted leaves can be a sign of stress.

perhaps the roots just aren't moving the way they want to, or it could just be nothing.

I would let them grow a little longer before trying to do anything.

Its nothing. Just the older fans showing signs right ???? No problem. Let her grow. Don't change a thing.

Cool, thanks everyone for the advice!

Feel like I'm an overprotective parent, but this is my first grow and I'm trying not to panic at the first sign of trouble.
