I just watered my plant and after hour or so the leaves are pretty droopy (only the ones near the top). I never noticed it happen before, so I'm a bit concerned abt this.
I water abt 1L/3days.
that is a sign of overwatering but your leaves are also suffering from nitrogen toxicity. that's why they are such a deep green. to dark.
want to lower the amount of N you are giving them. yellowing tips are another thing as well.
Good Luck!
