Second week started on August 28th. The pics show status of all 3 plants on Sept 2nd, 2021. I am concerned about one of the plants as it has not had any new growth for about 3 days now. Seems a bit yellowish as well. Withheld any water for another day to see if possibly it was overwatered. I have not started on any nutrients yet as from what I have been reading, it still a bit early to introduce. Any thoughts on the condition of the "yellowish" plant? Any cause for concern at this point?
