I am thinking you got a different Ph in each pot.

4-5-1 at half strength? Could be a potassium deficiency from the first picture and the NPK ratio.

Cannabis plants need more potassium than anything else in flower.

Okay then! How about hungry at half strength? Is GH known for running half strength? I had heard that about AN I think.
