Yeah, Green Cure treats PM really well.It’s a solid product.
Do you get any moths in your room where your tent is? The one bud you broke open looked like a classic caterpillar hatch. They eat their way through your bud, causing botrytis. If you catch them early, and pick them off you can save it and have less to cut out.
It may not apply here since you grow in a tent, but moths get into anyplace.
Even if it isn’t your cause, it’s how it happens outside. You have to really start combing over your plant after a few weeks into flower. An early tip, if you’re really beginning to pay attention, is that you’ll notice a few moths flying around you yard. If you see more than one, they’re here.
If I see any moths flying in the yard I start checking my plants by giving them a good shake, and lots of time a moth or two will fly out. They land in your plant and lay eggs or whatever they do to produce a caterpillar baby, and it grows up by munching right through the middle of the bud.
If it’s already farther along, while you comb through your buds look for any small brown spot and then investigate. If lucky, you’ll find the small worm and can pick it off and clip that bud and it won’t spread. A few years ago I had a huge plant with lots of large colas, and I only found out after I started looking and then I found a lot.
So, the next year, I was looking for the moths fying around in mid flower, and sure enough you’ll see them. I avoided any problems that next year because I would give the plants a shake a couple of times a day or more. Be careful, as I had one cola that was tall and by shaking the plant the cola broke off, doh!
But, at least where I live in mid September, I’ll see moths flying and then I go to work keeping them out of my plants. It worked great for me. I learned the hard way.
Ah, the joys of gardening cannabis…
