Strain
I think there was no desease involved in this grow, nor a single bug.
Got something wrong after a few weeks in flowering : brown spots everywhere on leaves that were solved by using pH-up to maintain watering solution at pH=6.5, everything else was OK.
It stayed low and thanks to LST (tie-down) it topped at only 35cm! Perfect for low tent.
I defoliated several times and it was essential as there was a bunch of leaves everywhere.
It took 15 weeks from seed to harvest : I could have harvested one week sooner but I waited for the good amount of amber trichromes.
