Hello guys! A friend of mine got a 4 meters tall girl, which is showing some deficiency on the upper leaves.
He water with plain water with ph on 7.3, the plant is directly on the earth (no pot) I don't have any more info from him, so I just need a simple diagnose please!
Thanks to everyone!

Thats classic MAGNESIUM!!!
You need to know, if you have deficiency or toxicity. Before you give magnesium or take some away.
PH?
EC/PPM?
Good luck
