I have a new flowering maple plant that is dropping it's blossoms and buds before their time. It's an indoor plant, gets indirect sunlight, and sits near a window cooler that is programmed at 70 degrees for 8 hours a day during the work week. During off hours, the office is warmer.

The leaves seem healthy, but each morning one or two have gone yellow. I wonder if I'm overwatering and/or the spot is too cool. All advice is welcomed...I love this beautiful plant and fear killing it. Thank you.
