Been growing here 20 years, just started seeing this last couple / few years. Read somewhere about it maybe being bad bacteria in the soil so last year I treated with "good" bacteria I bought but no help.
I'm growing 3 varieties outdoors: Skunk, Blueberry and White Widow. This leaf curl began on the Skunk and now a couple of the White Widow have it. So far the 4 Blueberries are not affected.
Could someone ID what's going on and of course any cures!
