Looks like the start of "canoeing" - cupping of the leaves.

Could be caused by excessive heat - how far from your plant is your light? What's the temperature in your grow room through lights on?

heloo ,
the light distance is about 30 inches, I happen to live at the equator and it's very hot here, my grow tent temperature reaches 90f when the lights are on

You need to have some why of monitoring the temp and humidity inside the tent. I am going though my first year with a tent and big LEDs. Suffering from the same. I used a temp controller for the exhaust in the summer and that took care of things set at 84F. But with the lower humidity of fall I found it's better to run the fan all the time. This gives me just a couple degrees above room temp and humidity levels slightly above room levels as long as the pots are wet and I hang a wet towel in there. I have a humidifier on order.

I was watching my flower room today and noticed the humidity started to drop below what it usually runs. I went in and they need watering.

I've been having problems with the 2.5 gal pots holding enough water for a day. That usually was the case until recently. And now even when I water the area around the base in the ball in the root ball is dry. So I'm leaving then set in the saucer with no spacer. It worked yesterday but I didn't water s much this morning.

Today I put a small mister in there on the timer. I doubt if it will do much good but the exhaust fan is a lot smaller than the tent. 80cfm IIRC.

If you can get some dry ice in a Styrofoam cooler, might help. It's frozen Co2 . If the cooling doesn't help the Co2 for sure will. But get that air circulating. asap.
