I am having a similar problem right now, unfortunately the pictures won't reveal much with this shitty camera. I too believe it is a calcium diff., but I am awaiting advice from others on the board. I also have slight curling of the leaves as you described on a few of the plants, if the nute burn isn't bad will it go away on its own? I only gave them 550 PPM and the plants are like in between 9-12 inches tall, I think they are plenty mature enough to handle that but I could be wrong.
razzapiggy Reviewed by razzapiggy on . Brownish Rust burns on plant leafs Hi, I noticed these brownish rust burns appear on one of my plant's leafs 2 days ago. Since then they have spread to another leaf but dont seem to be getting too out of control. :confused: Can anyone please tell me what it is caused by? It appears to be a PH burn of some sort, maybe. Please check out attached photos for reference. Thankyou.:thumbsup: DrKnow Rating: 5
