blotchy yellowing leaves on pepper plants
First post here. Hoping this works...
I've started growing pepper plants indoors (Jalapenos, bell peppers, etc.) using a 400W MH light and a 400W HPS light source.
My first battle has been with fungus gnats. I found a post that recommended crumbling "mosquito dunks" and sprinkling the crumbs on the soil. That in combination with fly ribbon has helped, but just started about a week ago.
My question is about a couple of my pepper plants. Their leaves are turning yellow, not all at once, but in a blotchy pattern. Has anyone seen this? Any ideas what could be causing it? Is this root-rot?
Thanks in advance,
