Fiddle leaf fig dropped six lower leaves two weeks after I moved it four feet Diagnosis

Put it back. Do not repot, do not feed.

The thing that catches everyone out is how fast light falls off indoors. Right at the glass on a bright day you might have 8000 to 10000 lux. Four feet back and off to one side is commonly 800 to 1500. That is not a trim, that is most of the plant's income gone, and a fig responds by shedding the leaves it can no longer pay for, which are always the lowest and most shaded.

Get any lux meter app and take a reading at the old spot and the new one at the same time of day. Nobody believes this until they see the two numbers side by side.

The second half of the problem is that a litre every ten days was correct at the window and is too much where it is now, because a plant with less light uses less water. So it is losing leaves and sitting wetter at the same time. Move it back, keep the watering the same, and expect the dropping to stop within two to three weeks. The leaves it already lost will not regrow on those nodes.

One diagnostic so you can rule out the scary version: push a finger two inches into the soil the day before you would normally water. If it is still wet down there, look at the roots rather than the light. Tip it out and check for firm tan roots versus soft dark ones that slide off like a wet sock.

Edge yellowing then dropping from the bottom up, starting right after a known move, with damp soil, is far more often light plus too much water than disease.

Do not fertilise a plant that is dropping leaves. It is not hungry, it is broke. Feeding a stressed fig mostly gives you salt build up in the pot and a plant that still has no light.

Also check whether the new spot puts it near a radiator or in the draught from a door. Figs sulk about cold air on the leaves and the timing would look identical to a light problem.

Mine did exactly this when we swapped rooms, and I panicked and repotted, which piled transplant shock on top and cost me another four leaves. Change one thing, wait three weeks, then decide.
