the yellowing on this plant is happeningfrom the stem out, but a few of the other ones are yellowing at the tips. they were watered 2 days ago, flooded half way up the 4in cube for 15 mins and drained.

no nutes dude-waaay too young-raise that light to 3 feet-too intense-hand water for week or so before going back to ebb and flow-ease up and they should recover but do back off
