This little plant hasn't grown for days and its cotildons are turning yellow. irrigation has a ph of 6.5 I don't measure ec and I use complete mix soil recently the stem broke ns if it has something to do with it
slight fade on teh first serrated leave -- so this is a yellowing starting at tip and moving inward (not interveinal chlorosis) It is also at the bottom of plant and creeping upward.
you can feel fairly confident it needs a little more Nitrogen. one way or another.
this could impact rate of growth observed recently for sure.
