Photos from digital microscope - for naked eye looks just like white dots size of sand grain.
It's exclay (LECA) from the bottom of airpot (there is soil on top of it - I can see the exclay by picking the airpot up and viewing it from the bottom).
I use tap water - which is highly mineralized - around 420ppm - I let it breathe 24-36h before use.
I saw simillar questions online - and ppl saying it's just salt, but it looks very sus to me. Although I should not have mould - there is strong extractor and fan operating 24h/day in the growbox - I don't understand how I could get mould in 2 weeks in fresh soil (BioBizz) with well ventilated growbox and airpots... This is madness... If this is mould I do not know how one would not have mould every time...
And if it is mould - what should I do? It's bottom layer, under the soil - I can not get to it without transplanting the plant - but this is auto and should not be transplanted. I got one small pellet through holes on the bottom of airpot to look under microscope.
