Is she okay?

For me it's an excess, the stem is red. The leaves slightly damaged. Too rich land or the fattening that started too early. It will start again, the next floors will get better and better. But it will have been delayed compared to the others, probably by a week. You can also remove the drip for a week and continue watering by hand. Obviously there is something she doesn't like. She is young, you have to give her some time to recover by changing some parameters 😉👍

awww shes looks a little sad not gonan lie. My guess is that the dripper is drowning her out. try to get her dried out the best you can and once shes 2 weeks old give her a little bit of nitrogen, and some cal mag. but go easy. I like the combo of liquid kelp and my organic cal-mag for most of the grow. I think she can overcome this though. It looks like you could use a little perlite in your medium It looks like pure peat, and lacking nutrients? I've wanted to set up some watering automation for my grows but it makes me nervous. To me I know if I hand water I have the most control. but if you can get it dialed in that's awesome. I think its important to get to learn watering by hand if you are a new gardener, I dont think most beginners are going to have enough experience to set up an irrigation system the most effective way. Good luck
