Blood looking

Kind of odd looking. I cut away a leaf during defoliation and the stem looks like it bled. Why did it do that?

Phloemsaft (Blutungen): Wenn die Pflanze eine mechanische Verletzung am Stängel hat, kann nährstoffreicher Saft austreten. Bestimmte Anthocyane (Farbstoffe) im Saft können diesen rot oder violett färben, ähnlich wie sich auch Stängel bei Stress oder Nährstoffmangel (wie Phosphor) verfärben können.

😍😍😍 hey buddy how are you my friend? What you’re seeing isn’t blood, it’s plant sap expressing itself after a fresh wound. When you cut a leaf or petiole, you open the xylem and phloem vessels. These are under pressure, especially in a healthy, actively transpiring plant. The sap that leaks out can look clear, milky, amber, or even red depending on genetics and chemistry. Why the red / dark color? Several factors can stack together: • Anthocyanins & phenolic compounds Some genetics produce higher levels of pigments (the same ones responsible for purple, red, or blue hues). When exposed to air, these compounds can oxidize and darken quickly. • Oxidation Fresh sap reacts with oxygen, just like a cut apple browns. This can shift color rapidly after the cut. • Carbohydrate-rich phloem sap During flower, sap can be thick with sugars and metabolites, giving it a glossy or resinous look. • Genetic vascular expression Some cultivars simply push sap more visibly — thicker walls, higher pressure, or different secondary metabolites. Why some plants do it and others don’t: This is where genetics really shows. Some plants barely weep at all. Others “bleed” noticeably. Neither is bad, it’s just how that plant manages transport and wound response. Important part: 👉 This is not disease, rot, or damage 👉 It’s not stress-related on its own 👉 It doesn’t mean anything is wrong In fact, many growers see this more often on vigorous, healthy plants during active growth or flower. Growers Love my friend and enjoy your bleeding girls 😍😍😍
