I'll have pictures in 1 hour, but till then i can only describe it.

There is a yellowing of the lower leaves on my biggest plant (still not that big 3 weeks old), And now my other two smaller ones are slowly developing it. Do you think its lack of nutes? are they old enough for them? i checked soil ph and it was light green which means under 7 above 5 (seriously such a bad gap lol).

What do you guys think

Short version: my plants have white spots on upper leaves, yellowing on lower.
