My 3 weeks old seedings start tuning yellow . Please see the attached photo.
Does anybody know what could have been the problem?
They are under the grow lights which I turn on approx. 16 hrs or so
Per day. Thanks in advance,
I can't say for sure, maybe they need a little nitrogen ?
I start mine in my own mix, also feed them a 25% solution of fish emulsion twice a week.
As I said before there may not be enough food in those small growing packets.
