double post sorry!
i have a plant doing the same thing, i was thinking its a mutation as well. Not mosaic virus for sure. I treated mine with a systemic insecticide and the weird jagged shit started. I'll snap a shot for you so you can compare. Looks identical to me though.
Months later - I planted out the seeds from the original sick plants and as you can see they are similarly affected.
lol 10k have you seen what alcohol does to plants?
