It's a few branchesThat could be grasshopper damage causing branch death. Is it just one branch?
We didn't have the damage until about mid flowerIt's a few branches
Grasshoppers are annoying af. They couild easily get a few branches. Do you see any around the grow? The rest of the plant seems healthy?It's a few branches
We have seen a few grasshoppers on other plants that don't show this damage but none on this plant. The rest of the plant looks good but the branches go from looking good to dead in a couple of days.Grasshoppers are annoying af. They couild easily get a few branches. Do you see any around the grow?

The plant is not oozing.Stem Blight. WOW.... I've never seen it on a weed plant. Cut those off and anything that looks damaged and get them away.
Damn....

Does that affect Cannabis? I can't find any evidence it does. It looks quite a bit different too.Stem Blight. WOW
Yeah they're easy to miss. If they even notice movement they will try to hide by moving to the opposite side of the branch. If you've seen others this very well might be the culprit. If you notice them they'll try to flee. if you don't this can happen in as little as a week.We have seen a few grasshoppers on other plants that don't show this damage but none on this plant.

That's what I was thinking. I looked up some visuals and it looks the same in some and very different in others.Does that affect Cannabis? I can't find any evidence it does. It looks quite a bit different too.
almost like a dogwood with insect attached. not blight!Any help identifying what's going on would be helpful! The stems are turning brown and woody. It is not killing all of the stems, but some are left looking like the second picture and just snapping off the main stem.
what he said and remove anything that resembles that.Not every disease looks the same on every plant. It presents based on the plant chemistry and physiology. Like I said, I've never seen it on weed. But I have seen it on corn and beans. Vicious stuff. It's a fungus, so treat accordingly.
You can use Nuke'em or Lost Coast Plant Therapy. We use the PT.
Spray it full strength, let dry for a couple of hours and then spray rinse to unclog the leaf pores or the plant will suffocate.
Thank you so much for your help. We will definitely follow your advice. We have also developed a better pest prevention routine. I truly enjoy learning and becoming a better growerHi CN.
I had one of our plant pathologists look at your photo. We both agree this looks like a nutrient deficiency, not a disease. I would not be worried about it from a quality perspective. You should make sure the soil or hydroponic water is an optimal pH and apply fertilizer with macro and micronutrients and it should clear up in the new growth.

Well, I thought it was a fungus, but the pros disagree. I have to go with them.Thank you so much for your help. We will definitely follow your advice. We have also developed a better pest prevention routine. I truly enjoy learning and becoming a better grower
We certainly needed to up our fungicide and pest management so your advice was still helpful...nice to know the pros tooWell, I thought it was a fungus, but the pros disagree. I have to go with them.
