what causes hard sections in satsumas

[keakar]

I tried one of my satsumas and half of it was hard inside and the other half was sort of half way between hard and normal flesh with only 3 or 4 segments I would call "normal"


those "normal" segments tasted fine but weren't sweet and had little to no flavor at all, but then its still early yet.


my question is, is there something that causes this, like lack of nutrients, or not enough water or something, or is it just something that randomly happens sometimes for no reason at all?


I only have around 12 satsumas on this tree because about a dozen got knocked off already cutting grass or by kids, most that are left are still green so I didn't try any more to see what they were like and will just wait another month or so for them to turn.


also these are at a property I don't spend much time at, so the only watering they get is from when it rains
