Ok please forgive me if I’m posting in the wrong section… newbie here.  🙋‍♂️ Thanks in advance for the help.

So firstly, I reside in Niagara Ontario Canada and long for the poolside summer days to be back lol.   With that being said, I recently took a trip to an open nursery and to my behold I seen this beautiful palm which I believe is a Chinese fan palm.   Please correct me if I am wrong as the the lady at the garden store could only identify it as a fan palm. 
 

Now my dilemma.  The first picture attached is of the palm at the garden store. It had some very light tip browning which I did not see as an issue and looked a good green colour. I could not help but think how good this would look beside our pool in the summer and be brought indoors for the winter.    In the meantime it sits our sunroom but we introduced it to the outdoors for a couple days just to give gradual exposure.  2-3 days at most.   Cold was definitely not an issue because the days spent outside were 68F or 20C plus.  We had a bit of an early warm front move in temporarily.   For the majority of the time it remains indoors where it currently is.  We’ve only had it home for 2 weeks but as you can see by the other pictures it looks to be struggling.  Burning tips, frond spotting and even spotting on the stems.  It looks diseased.   New shoots are continuing to grow fine, it was only fertilized at the garden centre which is still currently visible.  I’m just wondering if this is overwatering, underwatering, pest (nothing visible) or the fertilizer.   I know not to overdo it with watering but it did sit out through a good rain.  I’m refraining from watering in the meantime.
 

Please I need help.  Any recommendations are welcomed.  We don’t won’t to lose her. 🙏😊

Definitely time to re-pot those Chinese Fan palms into a larger container. Don’t worry about those minor imperfections on the petioles. 

You're overthinking it... The palm looks perfectly fine and has no disease. In the real world, you are going to see occasional brown spots,dried leaf tips, bug chews, wind damage, oldest fronds yellow, etc.  Absolutely perfect specimens are rare, are usually greenhouse grown, and will incur the minor imperfections you note if placed outside. Rainstorms can never over water it. 🤷‍♂️

Repotting is exactly what we are in the process of doing.  I was a little worried about possible overcrowding causing some kind of root rot.   Thanks for the encouragement to both of you.   

Sorry but just for my own knowledge.  Am I correct on these being Chinese fan palms?  I see Jim did refer to them as such but just in case he was referring to my posting.

Yes. That is a multiple planting of Chinese fan palms to give a fuller appearance to the pot.
