I bought an areca palm last week and planted in a combination of potting soil and sand in a large pot, outside in full sun. It's developing brown spots on some of the fronds. Is this a fungus or pest or just stress from transplanting? I have read that a common pest to this plant is the spider mite and that I should mist the plant twice daily with a soapy water mixture if they are detected but I don't know what a spider mite looks like or where to look for them!

I have not yet fertilized it and would like to know if it's okay to use "Bloom Burst" 10-52-10 or do I need something different and if so, what should I buy?

Does it need to be watered daily? 2-3 times a week?

Thanks for your help.
