DPM: First Try

Soybean Vein Necrosis Virus (SVNV). Root knot nematodes. Or Phosphorous deficiency either linked to hypoxia in medium plain old deficiency or both.

Looks like a pest but likey fungas. prob Rust. I think this is plant is gone.

Just checking but that is a cactus yeah??.. Jokes aside tho there isn't 1 answer for this, loads going on. Did all the pines just fall off or what?? Not a clue without a diary pal. No disrespect, much love 💚...

But the chances of leaf having blood blotch without purple red stems leads me to think it's 1 of the first two. Not that you were really looking for an answer anyway.

I don't think CaMg would fix your issues. Something is else is happening in that plant and we have no other information about it. Likely root rot if the soil is not drying out. the plant looks like it is dyeing and it stemming from its vascular system. but we have no idea how it was grown, what it was grown in, what it was fed, or anything about it. Try again, maybe start a diary from seed to harvest and see how you like the experence of it all on the site. Its kinda its whole thing. Grow-Diaries.
