Hey there Chris, yeah turns out you have caught the start of a problem. First off anything the leafs do is a reflection of how the roots are feeling. I can tell there's an issue from the red stems and stalks . Turns out this plant is a "low maintenance phenotype" and simply needs less nutrients that others or that it's at the end of the "feeding circuit" and getting more nutes than it needs. the plant shows signs of N excess as you can see from the 'too green" and "angry demeanor" of the leafs . try switching up the feeding rounds you're doing so that it goes first, or even reduce the nutrients you're feeding, you'll see improvements slowly over 10 days or so. The good news is you caught it early so you can fix it easily. Hope this helps ! 🚀
