Green Cleaner destroyed my plant. Should I cut it down

I sprayed one plant with green cleaner by central coast garden products and it completely murdered my leaves. I’m upset a store bought product should never destroy my plants. It’s been 7 weeks since I flipped my lights to 12-12 so like week 5. Is this thing too damaged to continue growing

I've been using it for a year just fine

There’s a picture

Did you spray and leave the lights on? I've been using this works great but I spray when there sleeping

What application rate did you use?
