I have no sleep so here's an update about the soil so far
My autos, 6 weeks old, germinated straight in that soil, which I did not rinse because I'm a tad lazy... Anyway, I added ~30% perlite and that was all.
It drains very well, it doesn't go muddy at all. It doesn't retain the amount of water I was used to but I liked it better this way. More frequent waterings with less water seems to give more control to me, and it's more forgiving if I mess up a feed

PH: I tested with distilled water before I planted, showed a straight 7. After the first couple waterings with ph adjustment to 6.5, the run-off water ph started going down. Now with my feeding mix at ~6.8 ph, and without ph adjustment, run-off water is between 6 and 6.2. Since the plants showed no deficiencies, I let it be this way.
4 euros for 15 liters of this soil is good, no?
Well, that's it I think
