Hi all,
I'm a new indoor grower and have recently noticed an issue that I can't quite identify. I've been growing 2 different plants in soil, White Widow and Mama Mia. The plants grew very well during veg and are currently about 2.5 weeks into flowering. Over the last week I have noticed black spots develop on many leaves of the White Widow plant. Over the last few days, the spots have increased in numbers and leaves with the spots have noticeable leaf yellowing. Leaves without the spotting look fine and healthy. Besides a plant disease, the only deficiency I could image this would be is a calcium deficiency...but I have been giving them low dose cal/mag and using local water which should have ample calcium. We did have some gnats in the tent, which I have since eradicated with fly tape. Not sure if this is related? The Mama Mia is completely unaffected and has perfect color and no spots. Both plants are fed/watered identically, which up until now has not led to any issues. I have been feeding at about 3/4 recommended strength and have not to date had much nute burn.
