What causes droopy leaf tips?

It’s hard to tell from the photo but , that looks like a sign of nitrogen toxicity, Leaf tips may turn down, without signs of overwatering. You may notice yellowing on the affected leaves or other signs of nutrient deficiencies as time goes on Nitrogen toxicity is often but not always accompanied by nutrient burn The Claw often seems random, affecting leaves here and there Heat and pH problems will make the clawing worse, as they stress out the plant and lower her defenses, and cause her to drink more water (and uptake more N) As time goes on, the claw leaves will eventually start turning yellow, getting spots, and dying , hope that helps you and good luck to you ✌️🏾
