I had a plant that developed balls a few years back,that i caused some stress with, i sprayed it with a product called optic foliar switch & transport guessing it was around 30. bucks & within 3 days all the balls turned yellow and would fall off at the touch,it truly
saved the plant & it did not grow any back smoke turned out OK.prefer of course not to use anything but in a pinch it worked for me.
I wouldn't spray that on anything I was going to be smoking. Couldn't get it anyway as it's banned in Oregon and Washington state. I can't believe what some in the cannabis industry are putting in their products without telling the consumer. Proprietary blend means crap that's banned in many places.
