Heirloom sativa, whats wrong with my plant?

So you flipped a month ago, you might have to flip harder.

Keep the ppms on the low end and keep your eyes on the roots. Shine a light and take a good look at them.

You haven’t mentioned your pH in all this.

It's currently set to 10/14(day/night). Should I lower it more?

14h dark should be more than enough... what about light leaks or breaks? sometimes the timers malfunction or have been accidentally set wrong...

No light leaks to my knowledge. Sat inside the grow space just before moving the plant in to make sure.
Timer is doing alright too, but come to think of it, all these problems started only after flipping

btw how big is your growspace for this plant actually?

48 x 56 cm or 18.9 x 22.05 inches.

did this plant ever flower? lol.

I'm glad you asked lol. It's barely beginning to flower. Still facing issues here and there but honestly at this point I'm just trying to keep it alive. Currently being feeding 1-1-1.5 at 400ppm (0.8 E.C). I think i might have magnesium deficiency or potassium. Other than that it's doing it's sativa magic and is gonna be a while before it starts to fill up.

I would chop it. plant looks sickly and is wasting space, time and power.
Sad but sometimes these indigenous and landrace specimens suck.
