No pests. I'm on my ninth year growing and I've never come across this before. All seeds are displaying this, no other plant in that tent, thats why I'm leaning towards disease
Had to look up "curly top beet virus" because ive never heard of it before but man, does that look right on with OPs plants.
I had one look like that it a while back, it was a very low ph in my soil....4.9 run off I added dolomite lime from suggestion I got here and it cured my isue up in a couple of weeks.....What is your run off PH?...do you add any ph down to your water? what is your base water ph?
No way that’s russets, damage like that there would be millions by now. And the opening leaf sites would be brown. Russets are very slow until their numbers are large then they take branches then plants the the next plant. And growing from seed they don’t just pop out of thin are unless he lives by a hemp farm.
