@Sweet_Seeds, no, it is totally new. this is the mix:
Peat mix: perlite- 1l, vermiculite- 1l, clay pebbles- 0.5l, peat substrate eco plus- 6l pH 5.5-6.5, some soil 6.5-6.5pH, mycorrhizae.
the first time it happened, i used only soil and it was also totally new pH 5.5-6.5.
didn't you see such things before? i have seen one more grower that also have this weird phenomena. i will try to find it and i will show you.
