I took the big Mother out for a photo shoot. I didn't dared up until now since she's so large.
I started flushing with RO water.
Unfortunately I got mold on two buds, one on the large Mother and the other one on one of the other ones. Now I placed the dehumidifier inside the tent and set it up to 30%. I really hope this helps, cuz they look like they could use ca. 10 more days.
@Cyrusdavirus,
Thanks! I must say I was a bit time pressured, so I've only topped them twice and LSTed the main branches. But even so I'm pretty happy with the results :) Thanks again! ;)
