@auto noob , I found it, i had just missed how much they had grow for the last week.
I saw the best growth so far in 12 hours on one of the girls, so i decided to do a raz-change and bump at the feed a bit. They should response quickly.
SM-90 works for sure. Since last week no more slime has developed, if its something, its like 5-10% of what i had. Now its just a little, little, and nothing to worry about.
I was worried about the difficulty when doing rez-change, but its an piece of cake.
Im still a bit worried to do a mistake by adding something wrong and mess it up, as the roots get affected
Immediately if so. In soil, you have time to fix it, or atleast it wont hit that hard.
Overall I think im in the game. The look of the girls, even they are small, is that they are healthy and looks the same.
Ill do a update in a few days with some pics.
