FIX Purple stems FAST with these 3 things!

Purple streaks on stems and petioles aren’t “just genetics.” In this episode, Brandon Rust breaks down how to diagnose and fix purple stems fast by: (1) balancing base cations for proper mass-flow, (2) dialing light intensity and canopy temperature to remove oxidative stress, and (3) restoring phosphorus availability and diffusion. What you’ll learn: Target paste/solution balance: Ca ≈200 ppm, Mg ≈32–40 ppm, K ≈100–150 ppm; keep Na low. Why VPD, transpiration, and water movement govern electrolyte (cation) delivery. How excessive PPFD/DLI under LEDs drives anthocyanin “sunscreen” and purple streaking. Phosphorus moves by diffusion (not mass flow)—and how Ca/Mg, pH, and micros can precipitate P. Quick fixes: rebalance feed, adjust light height/dimmer, match room RH to temp, support P cycling.
