Leaf Tips Slightly Curled

Hello fellow RIU posters, i have a small concern about my babies. I was in the garden this morning and noticed a small curl in the leaves. There is no discoloration and the plants look phenominal. My concern is though i checked my PPM and it read 1900. This has been rising significantly and i was worried that the curling might be a cause from over nuting them. Tommorow is resevoir change day, but i dont know if i should change early. Its a 45 gallon resevoir and nutes are expensive but IDK if rocking 1900 for another day will be bad for my babies. I have posted a picture and hope someone has some feed back.

Thanks and Happy Smoking

What's the temp in there?

What type of system? I think 1900 ppm is to high just dilute the rez with water but it does look like a heat issue also.
Hope that helps.

looks like heat stress

Temp was 82 F, and its a 1000 watt light, prolly right too hot, i am venting now, but yeah i changed the res got it down to 1560, thanks for the info guys!

keep on dropping those ppms down. way down

My ac went out and my room got up to 95 and that's exactly what happened. now I have an extra ac and 8 in exhaust.double up, it's expensive but definitely worth it.
