Hello, I am a new user here, I am looking for help ASAP, I am shocked. I am growing 3 hectares of hemp. The babies are in week 4 after planting in the field. They are still in vegetative stage. 4 days ago I fertilized them according to my fertilizer's plan. Nothing out of order. On the very next day I noticed black spots on the leaves on almost every plant. 3 days after that, the spots became golden/brown. Pictures attached. PLEASE help guys, I invested a lot of money and I am learning a lot, but still got surprised...
