  3. That type of leaf curling (tacoing) is caused by 1 of 4 issues. Heat, to much light intensity, high humidity or possible magnesium deficiency.

  4. raise the light . your to close is this an open hood ? plants are smart they will reject to much light by doing the only thing they can . they try to close there leafs up there telling you its just to much light . soon these plants will be able to walk around in the room and feed them self or take the family pet for a walk lmao .
