My friend had to move today and could no longer take care of his plant so he gave it to me when I got her home I was looking her over and I turned her around and I saw 2 other little plants leaves resemble cannabis and I asked my friend he said he has no idea but they look like weed to him lol idk they do look like weed but I think it's weird there at like 5th node and still a bunch of little one finger leafs on Every node both plants not a single multi finger leaf can anyone shed some light on the what how or why there are doing what there doing an why look so strange thank you a million to anyone who can help here these little things hurt my brain

Hi 405, Well for one thing, they aren't getting enough light, so they're stretched out. Try transplanting them and staking them with a skewer or something you have on hand--they will need some support when you get them in the light.

'Roun' here we call them Piss Elms! They will make a huge tree you dont want your car under in the summer (you'll find out why we call them piss elms!). I pull them every few days as they come up where ever I find them on my place, and kill the big ones.

I plucked the.fat one cause I'm 98% sure that was a type of vine but the weird one that looks like cannabis but just with only finger leafs and yeah you thought it wasn't getting light but when I got it from him he has a nicer like 600w or something that's what was vegging the plant with the little twig in it's pot and the twig is like 8 inches away from the whole plant so he isn't even being shaded if it is cannabis something is seriously wrong weather it's a male or mutant I don't really want it I might leave it for a week just to see how slow it grows but yeah he said he got the plant as a clone got it home transplanted her the same day and he said it was like 3 days later when that thing popped up and that's almost a month ago..... So it's the size of a light but stem is super tiny but it's like hardwood feeling doesn't feel bendy at all so weird for a seedling....
