Watering with CalMag and Simplex PK Boost (1 ml/L), then lowering pH to around 6.0–6.3. Adding 5 drops of Simplex pH Down – I transferred it into a 10 ml dropper bottle (from VitaS stimulator) for easier dosing without a pipette.
Three days ago, there was a heatwave, and I left for the mountains for a few days. The plant got dried out – leaves drooped. Realized I need to upgrade the 3L auto‑watering tank – it only lasts two days max. Switched to a 5L tank, but a 15L canister with a drainage tray would be better. That would easily last 3–4 days. At +29°C, the plant drinks and evaporates at least a liter per day.
Other than that, leaves look healthy, buds are beautiful. IZI is delightfully low‑maintenance :)
Watering is done with an auto‑watering pump (1 L/min flow rate) – 5 seconds every hour. There’s also an airstone in the solution for mixing and oxygen saturation.
The plant has slowed down in vertical growth and is now bulking up the buds. I’ll continue feeding PK Boost for another 3 weeks, then a flush – and then wait for harvest.
