Update day 44: the side branches are developing very well. I quite like this pheno. No training requires. She started flowering now. She is suffering from some problem, which I suspect is a lockout because I have not been watering till runout. I fed her today with 1L so plenty runoff to wash away salt buildup and she seems a bit happier now.
Update day 48: everything is going well apart from a calmag deficiency that is ongoing since the start. Some of the few calyxes she has now are turning purple!
@Fast_Buds, thank you very much for the opportunity! Sadly, I was attacked by some nasty pythium this cycle and one of them did not make it. The other seems to have survived it though!
