Unseen problem on leaves and roots

Post by ppavlov84 »

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...

Looks like over watering from what I can see. Any chance of some pics of the whole plant to see where the issue is appearing?

Looking at how the damage progresses, this could be a fungal issue. As @GMO said, I'd like to see a couple more photos before saying for sure.

To me it looks like fertilizer burn

Did you spray from above or do you use a drip line? It looks like what happens when salt fertilizer dries on the leaf and scorches it

That doesnt look like a contagious disease to me. It looks like some abiotic stress.

Curious about how you applied the fertilizer and what it was that you were using
