Curling up/cupping

My plants our cupping or curling upwards how can I stop this

Looks like heat stress . How close is your light to the plants . Try backing it up and see what happens . Only other thing I can think of is root issues . Rot issues can present in a number of ways . Stunned growth discoloration and even cupping of the leafs . I would start with these 2 things and go from there . I would bet it’s the light tho .

Sure sign the light or the space is too hot and likely dry. What's ur rh?

All good advise above!
I see a plant that has - too much TLC- (everything) (not certain about amount of air circulation)

I would stop N-raise lights- stop watering unless the pot is completely dry.
Give Si and some root enhancer.
