I got a new fiddle leaf fig about 3 weeks ago in the mail, it was healthy and spent at most 4 days in shipment. When it came, I watered it and two days later repotted it into a bigger pot (with drainage holes) as the one it came in looked very small. I used Miracle-Gro all purpose soil with a few pebbles laid on the bottom of the pot.
It's been sitting near a south facing window and gets plenty of indirect light during the day. (Sometimes a sliver of direct light passes over it and I try to move it out of the way for the hour during the afternoon when the sun passes in the exact spot.) I water with rain water (or filtered) only when I stick my finger in the soil and it feels dry (but not yet crisp) and then I sit the inner pot in the sink for an hour or two until it stops draining before putting it back into the outer pot. This works out to be around once or just twice a week. I've fertilized it once with an all purpose Miracle-Gro liquid fertilizer since having it.
I noticed the tips of the leaves starting to wrinkle a bit (please see pics!) about maybe a week ago and I thought it might have to be with my watering technique at first. I've done some research and it doesn't seem like I'm that far off with what I'm supposed to do. This stresses me out because apparently this can happen with too much or too litter watering?!
I read that it might have to do with problems with pests, especially after noticing a couple of brown spots on the underside of some (though not all) of the wrinkled areas. I checked for spider mites and mealybugs at all the crevices and underside of each leaf and haven't seen any signs of these! I did have a slight problem with these tiny small fruit fly-like flies (don't think they were fruit flies because they're not attracted to vinegar or fruit traps) but since I've put up traps and put some layers of washed shells/pebbles on the top of my plant soils, they've not been around. There's now a drying crispy lesion on one of them that goes through the full thickness of the leaf (second youngest). Pictures attached.
The wrinkling started at the tips of the leaves and now has been spreading slowly down the stem towards the base. They're affecting all the leaves except the 2 oldest ones.
There's a single new leaf bud forming and it's gotten larger but only slightly.
Please please can someone offer any insight or advice on what on earth I'm doing wrong?! Or tag someone who's an expert on finicky fiddle leafs? I'm really worried!
