GMO × Triangle Mints BX – Week 12 Veg | Growth Surge, CalMag Issue Spotted and Corrected
She’s responded to the warmer weather exactly as expected. Up to 110cm this week, canopy has spread wide and the branch structure from the earlier LST is really starting to pay off — plenty of well-spaced tops developing underneath.
Not all good news though. Mid-canopy leaves started showing interveinal yellowing — classic CalMag deficiency symptoms, traced back to pH drift affecting uptake rather than an actual shortage in the feed. Switched over to CANNA Aqua Vega with added CalMag Agent and dialled in the pH more carefully. Seems to have arrested the issue, at least from what’s visible so far.
She’s now running the same feed schedule as the indoor plants — two feeds with full nutrients, one feed plain water. Nutrients: CANNA Aqua Vega 4ml/l, Canna CalMag Agent 1.1ml/l, Aptus Regulator 0.1ml/l. LST ongoing.
The forecast ahead is looking like the best stretch of the season so far — temperatures potentially hitting 30°C next week, nights staying mild, winds light. If she stays healthy she should put on serious mass over the coming weeks.
Updates every Sunday. Stay tuned. 🌿
