I also have two cbd plants currently growing with quite a bit of variegation on them. The markings are identical to those I see on your plant, tho mine are colored more yellowish. (can provide pics if needed)
Interesting. It's called
interveinal chlorosis – i.e. "abnormal reduction or loss of the normal green coloration" between the veins of the leaf. This is exactly what my plant is showing, all over the plant, and also wrinkling and abnormal leaf margin (edge).
Yes, I would like to see your pics!
I'm not saying I'm 100% certain it's the Cannabis cryptic virus, but the symptoms and photo match – according to the one source I found.
Here's the plant (Aug. 2)... this is the clone that's currently in flower:
here's a close-up of the chlorosis, wrinkling, and affected leaf margins:
It's my feeling that a virus wouldn't leave the leaf looking strong and healthy still, whereas variegation will. That's how I think of it anyway.
I'm glad you brought that up. Yes, the distinction between virus and variegation is that the virus symptoms are adverse – i.e. they have a negative effect on the plant. Variegation is completely benign.
The odd thing is, my affected CBD pheno gave me a very nice yield of big buds last time around!
Apparently, iron deficiency also causes chlorosis (maybe not interveinal), so maybe some phenos are more sensitive to iron deficiency than others.
Here's the same pheno (previous clone) in flower on June 14
here's a close-up of a big fan leaf in the above cola – the chlorosis is there but barely perceptible
Here's a bud close-up... there's no chlorosis. Why?
Strange, isn't it? If it's a virus, it's not causing any noticeable harm! The chlorosis varies from one clone of the pheno to another – sometimes lots of chlorosis, sometimes barely perceptible. Now it's starting to sound more like a nutrient deficiency... iron? I wonder. Perhaps pH is involved.
I just read an article talking about using grafting to determine if a cannabis plant is infected with a pathogen – i.e. take the rootstock of a suspected plant, and then graft on a healthy plant. If the rootstock is carrying a virus, it will migrate into the graft and cause symptoms.
