Hello everyone! This is my first time creating an account on the forums here and I just was wondering if I could get your guys' help with identifying something that is happening to one of my babies. About a month or so ago (can't remember the exact amount of time it has been happening) one of the nodes on my plant began to show signs of its leaves turning black and twisting around themselves. We thought it was just a nute deficiency, but it is still showing up and spreading down (or up, not really sure which way it's spreading on the arm) and seems to show no sign of going away. It was originally in a 5 gallon bucket, and has now been transplanted into the actual ground itself, and as stated before the issue has been presenting since before we transplanted. I do not know the strain of the plant, and it is being grown in Michigan. I haven't been able to find anything online that's similar to the issue that I'm having, and I really hope you guys can help me out. Pictures will be included at the end of this message. Again, they are turning black on the leaves and bud, the plant is now two weeks into bud, and it IS spreading. I'm worried about it making its way all the way to the base of the plant and then spreading to the rest of the arms, possibly corrupting the rest of the plant. Should I cut that arm off? Is there something that I need to add to the soil like calcium? I'm honestly freaking out haha. Sorry for the low quality of the images, my phone kinda sucks. All pictures provided are of the one plant, and if better images are needed I will be taking more today. Thanks again everyone, stay safe, and toke on! Edit: The leaves don't feel dry or dead, they still feel smooth and alive, it's just twigging me out how they are turning black and folding/ twisting on themselves. Will get better pictures hopefully tomorrow/ today if I get off work before nightfall. Edit 2: Also the plant was potted only in promix when it started to show the issue described and shown in the pictures, and then when it was transplanted into the actual ground we dug a hole larger than the plant and filled it with a mix of promix and happy frog organic soil so it would be in better soil than the actual soil we have.
Nothing lower than 55. We're having a pretty warm summer actually. Definitely not cold enough to cause any harm to the plant I'd think, since it's only the one that's having the issue. All my other ones are doing great.
