Diary Update: Week 3 – Substrate Management & Climate Tuning Starting tomorrow, I am bumping the light intensity up significantly, targeting a DLI of 38.88 to push vegetative growth to the max. To support this high light energy, I am using the Plagron Terra mineral line (Terra Grow, Power Roots, Pure Zym, and Sugar Royal). Because my substrate EC is currently under 0.2, raising the nutrient levels is urgent; otherwise, the plants won't be able to keep up with this high DLI. I will gradually increase the Terra Grow and additives this week to hit that target substrate EC of 1.0. I'll closely monitor the two slower-growing plants to ensure they don't get stressed by the intense light while their root systems catch up. Day 18 - In the previous days i had the soil probe on the top of the pot to see how the water levels/ec would do. But it seems that the ladies are quite demanding and i will up the EC to 1.5 at this stage. Today i shall move the soil probe to a horizontal positon halfway in the pot and give each pot about a liter of water (see when the soil probe goes up to around 30%)
