What is seen in the photo appears to be okay, but it looks like you have trimmed off the brown tips. Keeping the soil moist is the key to minimizing leaf tip browning. I suggest that you water as soon as the surface of the soil feels dry, a bit sooner than you have been.
Always water thoroughly so that some water drains through the drain holes. Use filtered or distilled water in your tap water is hard. Misting is unnecessary as long as you keep the soil moist.
Provide maximum indirect sunlight.
