Spray damage?

Sprayed my plants yesterday with green cleaner at 2oz per gallon and today the top leaves are curling bad don’t know if it’s a coincidence and something else is causing the problem or damage from spraying.

Did you spray them at night? They also recommend starting with 0.5oz to 1oz per gallon of water, before drenching the plants with 2oz per gallon, to make sure they plants don't have a reaction to it.

Yes I sprayed them about a hour after the lights turned off and had previously used the product without a problem.
