Some clones look ready enough (pics) and I don't want the big plant to stay in veg too long. So I've decided to plant the clones and see if they grow well.
Anyway, I'll switch to 12-12 in 3 or 4 weeks.
Applied some biobizz alg-a-mic and acti-vera (very light foliar spray).
Applied nematodes again: other vendor, the previous applications didn't seem to be very efficient.
PS: lights still roughly at same height and intensity (45%)
