Need help identifying leaf problem

This is the second crop I have dealt with this issue. Both crops grew very slow during veg seemed healthy but have some alligator skin like leaves as shown in photos. I'm not too experienced with deficiencies or toxicity. Last crop that this happened on I assumed I had been sold expired nutes and decided to go with a completely new line for the hell of it. Used to run heavy 16 now I am running emerald harvest. If anybody could shed any light on this it would be greatly appreciated.

Do you have a scope? Have you inspected the leaves and plant for bugs? Do you have a pic of the whole plant?

Looks like white flies. I had similar problem

Yeah, at least until a pic of the whole plant becomes available, I'm leaning towards whiteflys as well. While I do see some N toxicity in the bigger leaves in your pics, it doesn't explain those blotchy spots, I'd try to inspect with a scope or loup and see what ya can see.

Pests for sure...and if you're carrying them from grow to grow, you'll need to do an excellent job of cleaning up your grow or it's going to be ground hog day all over again. Good luck friend.
