That's right in the middle where your par is highest. Can you move your bars around on that light? Add a better fan. They do t look bad at all.

No unfortunately I can't move the bars ..add a better fan ? I already have 2 fans inside 1 exhaust and one intake that's more then enough air movement I got temperature down to 73 humidity at 65
Light is 3 feet away 36 inches

They look great just that issue with one plant of the leaves cunning and curling up but I really doubt it's light or heat I got a sensor to read the light and it's at 450-500 is that too high for them

For one, Id get the temps back up top 80f-82f. And theres basically no such thing, as too much fresh air exchange. Shoot to get all you can.
A bit higher temps, will help the plants metabolize faster, using more food, and water.
Also looks like they may have the beginnings of Calcium Deficiency.
What are you feeding?
Many things can look like a deficiency, or overdose ect.
Calcium deficiency, can cause leaf tacoing.

So should I put the light back to 60 percent power to get temperature up to 80-82 .
I am giving them
Fox farm grow 10 ml per gallon
Cal mag 5ml
Flora micro 5ml
Hygrozyme 2.5ml
Gave them espom salt 1 week ago for calcium
I really need any advice I can get

Before raising your light intensity, What is your PPFD at the top of your plants? If your PPFD IS LOW, You can turn up your lights. If it's in range you have to set your lights higher in the tent before increasing the light intensity.
I follow this chart.

Plants are at 450 ppfd

It should be ok to turn your lights up to warm up your tent temperature.
I'm running my veg at 600 PPFD.

That won't solve my problem of the one plant leafs cunning any opinions on that?

I’d lean toward magnesium deficiency judging by purple stems, taco leafs, older fan leaves. Also maybe nutrient burn or lockout shouldn’t be ruled out. What medium are you in? Have you checked runoff ph? I run a mixture of promix and perlite and noticed I get magnesium issues with high light intensity coupled with low runoff ph. The epsom salt you added a week ago would have been likely to increase magnesium not calcium. I would foliar spray with epsom and see if you see positive results before examining your nutrient ppm levels.

Ppm levels are at 750 run off
Soil is Fox farm strawberry fields
So I should add epsom salt to there watering I added it Because I thought it would help with magnesium and I already did foiler spray too also
And I give then cal mag not sure if that helps also am new too all these am not a pro so all the help is appreciated

I don’t have a nutrient breakdown for the fox farm grow but I’d say you should look into your nutrients. I use 4-18-39, calcium nitrate, and epsom salt and gh micro which is about the cheapest and most customizable if you want to look into it. There is a few nutrient calculator excel sheets floating around the site perhaps download one and play around. Rough ratios for Potassium, Calcium and Magnesium are critical. Ideally 3:2:1 respectively and closer to 4:2:1 into flowering. Also NPK ratio should be 2:1:3 or 1:1:2(Lucas formula) respectively.
Since it’s one plant right now I’d definitely check runoff ph on a couple and compare. If runoff is on the lower end could be lockout coupled with insufficient ratios.

Do you think I should just flush then if run off is low ?

I am going to water tomorrow and al update you on the run off ph
