I’m also in upstate NY where we’ve had the rainiest summer in a century. Plus 40 degree nights recently. Could be a root issue. The other plant of the two, which were grown from seed, is doing better. I might just chop it down in the next couple days,, trichomes are milky with some amber.
I’m feeding with 0-51-34 booster and CalMag. She just shut down on me in the last week or so. Started from seedling mid April, been outdoors in 7 gallon bag since.
