if the leaves are green but droop down, you're underwatering. If the leaves start to yellow, you're overwatering. it is what it's called. a weed man. she'll survive some horrid conditions, but just let the top of the soil dry out a bit before watering, possibly once every 2 days. i don't know thats just what i do, it all depends on temperature and humidity. Goodluck and Happy growing!
overwatering and too much nitrogen. Lots of your leaves are canoeing. Id let them dry out, water twice the volume of the pot with straight water, then next water go easier on the nutes.
