Lemon Jeffery - SOG Grow

Week 2 - Lemon Jeffrey (FEM) Lemon Jeffrey by IRIE Genetics (6 Starts for 2 Finishers) 63-70 Days Flower (9 - 10 Weeks) Summary Goal this week was simply to have happy seedlings. I over-fertigated early in the week - let them dry down for 24 hours. Fed 60 to each as a flush (really just wanted known moisture level), then 30 ml/ each twice a day since. May have errored with mix Tuesday, pictures illustrate two plants with nutrient burn. Leaves have remained yellow/green until today, where so me darkening in the center growth is apparent. A little late Sunday watering - all well. Fertigation - 30ml/plant - EC: 0.85, [Primer A, Primer B, Silica Skin, Lush Green, CalMag Fuel, Root Anchor] Have Week 2 Base mix in the fridge.

For production flowers - we’re looking to MAINTAIN 40 DLI Through Flower. - This means we’ll need a MINIMUM PPFD of 930 to achieve at 12/12 We’ll run flipped Light Schedule. Dark hours are set at warmest part of day to support temperature control.
