What is happening to my plant

If anyone can tell me what causes these leaves to do this it would be greatly appreciated. thanks!

Looks like a zinc deficiency., maybe early potash def? What are you feeding your plants?

I'm feeding them fox farm nutrients
Grow Big, Tiger Blood and Big Bloom

In what medium? How long in the medium before you started feeding them with this? At what dose are you feeding? Etc.......

Looks like common light burn to me.

My opinion is light burn man,

Maybe feed a lil less, fox farm nutes can really lower ph. Have a fan blowing between plant and light.

I think you're feeding her too heavily...
