greenAFanswered grow question 1mo ago dont matter even if they were all cuts of the same plant, in the same tent, with the same exact feeding sched, each plants its own organism and can have isolated issues, and with seeds that adds another layer of variables on top. To me that looks like root zone stress, either down to watering sched, the feed, or both, to me they are all showing overwatering stress, the worst being the small one. Obviosly a less established plant will have a harder time dealing with that and will slow it down. Id let that one dryback more, unless you watered right before snapping the pics and they prop back up after watering thats what I would do.
