Leaves clawing

I started using bud candy and did a run with hygrozyme during the first two weeks of bloom. The leaves started clawing down. What's the problem you think? The ms/cm was 1.28 last night. The co2 was around 1750. I turned it down to 500 ppm. It was accidentally turned up to 1750.

Pics is what people will ask for mate sorry first grow cant help but intrested
