My Stems are changing color, from Green to a Red/purpleish color, the plant otherwise Looks good and is still Growing. Do I have to worry about the Red color or can some more experienced grower Tell me what that is? On both my plants.

if it's just the petioles (stem refers to branches/trunk, but petioles are for leaves), i wouldn't worry about it. Especially if it is mostly just the petioles exposed more to light. you can look up a leaf symptom chart and it'll say low P or something is a potential cause, but this shit happens under an LED. So, if you don't have any coinciding visual effects, it probably has nothing to do with a deficiency. plant looks healthy. probably nothing REd and purple can be genetics too. IF you see read/purple streaks in stems (not petioles) this can be low S... again, you usually need to cross-reference more than 1 visual clue to accurately diagnose things, and even then it can come down to a best-guess. Visual symptoms are not discrete. Relying soley on leaf symptoms leads to false-positives and mistakes. Use all the info avialable.

Red/purple stems are usually nothing to stress about, it's often just genetics or light intensity from your LED. If the plant looks healthy and is growing fine, you're good. Could also be mild mag deficiency, so tossing in some Cal-Mag once a week won’t hurt, especially with Biobizz Light-Mix. Keep an eye on new growth, if it’s green and happy, you’re golden.

Purple or red stems are common and often purely aesthetic, especially in pigmented cultivars, during final ripening, or under bright light. They become a diagnostic flag when combined with leaf discoloration, tissue brittleness, slowed growth, or tip burn. Use visual pattern, environmental logs, root-zone measurements, and sap or tissue tests to decide whether intervention is needed.

They look fine so it will most likely be the strain.Iv got Pulp Friction and Pecan Pie on the go and the stems of the PF are really purple but the PP is all green.
