I bought my fiddle leaf from Amazon (probably not a good choice) in last October. And it wasn't great at beginning. This winter I started to notice some brown spots. It took me a while to see the web around the leaf to realize it's a pest problem. I tried spray neem oil mixed with water on leaf as instructed. Now I see less web but still a few. There is a new leaf appear at top recently however it already had some brown on it (first photo). I place it near window but not too close. Water every 5-7 days when the soil is dry. I am still spraying the neem oil water now and then. Interior temperature should be around 60. I never re-pot it. I have try to put in Miracle-Gro Indoor Plant Food spike in the soil. Not sure if it's making any differenct. The soil seems a little hard. I am not very experienced with plants and looking for help and advice to save my plant. Thank you in advance!!

Fiddle-leafed Figs are quite pest resistant. Where did you see the webs? On new leaves just emerging or older leaves?

The leaf spots are caused by lack of light and letting the soil get too dry. You cannot give this plant too much direct sun when indoors, so move it right in front of and close to your sunniest window.

Likewise, if it is still in its original nursery pot, then it is pretty hard to over water. Water it thoroughly as soon as the surface of the soil feels almost dry, but not completely dry.

Unfortunately, the damaged leaves will always have those spots unless you trim them off. However, with better light and watering, new growth leaves should be fine.

Skip the fertilizer spikes. You can use any liquid fertilizer at half strength but no more than once per month. I also suggest you stop using neem unless you have identified a specific pest.

Thank you for the advice! I will try and see if any improvement. There were web around the some existing leaf and tiny whitish bug on leaf. I think they were spider mites. Haven't spot any recently so I will stop the neem. Thank you for the advice again.
