Hi, this is my first time growing and my first post as well, so please forgive me if I’m posting this in the wrong place.
So this plant strain is called Blue Mystic. It’s outdoors in Black Magic potting soil, a 20gal fiber pot, it’s been fed Mills A+B as well as Mills V and R with periodic cal/mag and Neptune’s harvest fish+kelp in water pH’d around 5.8-6.2 range.
I topped it about a month ago. One of the main stems of the plant is the one I have taken pictures of here. I’m not sure why only one stem looks this way. None of the other plants of the same strain look this way. One other plant, a Somango, has one set of new growth that has some lighter coloration like that, but that’s it. Other than this the plants look really healthy.
Is this a deficiency or a bug? It doesn’t look like fungus or mold, just more so a pigmentation in the leaves and going up the stem like lines. I don’t have a PPM meter unfortunately, so I don’t know what the run off is. I’d really appreciate any help you can give me on this. I’ve looked around and couldn’t really come up with a definitive answer on my own. Thank you in advance!
