The first two pairs of leaves suffered something..I think either the lamp was too close (I increased the distance) or the water was cold (<17C, now really 20C)
As soon as I remedied these, the growth started.
So far, I'm satisfied..
The training will start next week after the lady is put in its final pot, with a dripper.
