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.

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

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 .
