Hello.. Hope you are well.. I just had a quick look at ur dairy n noticed ur in soil..
@2wks old they will need nothing but sparingly watered with plain water
@ph6-6.5.. Personally if uve just super charged soil by accident and because they so young(completely flushing will drown her roots).. I wud just try to repot her asap.. In fresh soil if possible.. Ive chucked many 10ltr buckets of solution because i got distracted and added sumthing twice by accident.. We all do it now and again.. Stay safe n gud luck with her.. 👍🍀
