>>1081074My potted ones have entire yellow leaves that eventually fall off (the older ones) so I guess I'm underfertilising a bit.
Have you consider planting them outside? They grow like 10 times as fast as when kept in pots it seems.
Here a comparison pic with both (from the same fruit, both sprouted Jan. 2016 - one planted last summer, one kept in the pot, had been same size until then. Also I just moved the potted one there for the pic, normally it is in a place with even more sun than the ground-planted one)
