Day 73
The plants look healthy and deeply green. First buds have appeared — flowering is going great.
Over a week ago I removed the base nutrient Simplex Coco. Now running only Power Feeding Bio — mixed it into the coco and topped the substrate with it. Watering with plain water at pH 5.7–6.3, CalMag, and flavor additives at 1–2 ml/L: Simplex Aroma Punch and Taste.
Previously these same plants showed nitrogen toxicity — red petioles on the large fan leaves when using Simplex Coco base at 2 ml/L as per the manufacturer's feed chart. On bio nutrients and water, new growth is coming in clean. Some leaves still show minor spots from previous acid overdose.
A week ago I ordered basic pH and TDS meters from a local marketplace. Now dialing in the water properly: first bringing TDS to the target level with CalMag, then adjusting pH down with Simplex pH Down. Sometimes as little as 1 ml of acid is enough for a 15-liter bucket.
The new auto-irrigation system arrived — in the coming days I'll set up drippers in the substrate and find a 5-liter reservoir for the tank.
The speed at which the Durban plants have started flowering in a fully blacked-out tent is impressive.
Waiting for some fat buds! 🌿
