Don't spray the plant unless its a specific treatment (Like a epsom salt treatment). Water the soil, not the plant.
I can't say it looks too terrible, but we can't really see how wet the soil is.
Something to try, Fill an identical pot with soil, let it dry out, weigh it. Record dry weight, then water the empty soil pot with water until you start to get a little runoff, once the runoff stops, weigh the watered pot. Record wet weight, and now you know about how much water it will take. I read the soil drying out is an important part of the whole process, so if you never let your soil get somewhat dry, you may be overwatering.
