The necrotic leaf tips/margins are almost surely manifestation of a drought response, but there is no way to tell if the issue is from under-watering (probably not, unless the plant has wilted often because of a soil too dry), over-watering (most likely), or a high total dissolved solids (TDS, salts) in the soil solution, or a combination of over-watering and high TDS.

A TDS issue becomes more likely if you've been watering in small sips to avoid the probability the soil would remain too wet, too long, and in doing so, inhibit root function and have a negative impact on root health. To flush the soil and rid it of unwanted dissolved solids, first saturate the soil and let it sit for 10-15 min, then run room temp water equal to at least 10X the pot volume through the soil, even if it's a BIG pot. When it stops draining, tip the pot at a 45* angle and note how much additional water exits the drain. Here's why:
