Gorilla Zkittlez in mineral wool

Day 78/35: Added a bit more of CalMag (1.35 ml/l), raised inflow EC to 1.4 (704 ppm). Signs of Calcium deficiency visible on older fan leaves. Will remove the most damaged ones tomorrow. Other leaves look pretty healthy with nice green colour. Keeping runoff at 30%. Should be 3 weeks to go. Going to switch to Final Part (Ripen) by the end of this week or a bit earlier for at least 10 days, then flush with FlashClean for 24h, and finish with only tap water for 3 days. Reduced humidity by adding intake fan, that has about 90% capacity of the current exhaust fan settings, to add some pressure inside. How didn’t I know that earlier. Exhaust fan with carbon filter and passive intake with dust filter reduce the pressure in the tent to a such degree, that the fan efficiency decreases and it is not able to evacuate enough volume of humid air. Humidity was building up to 65% day / 70% night. Adding intake fan helps the main fan transport higher volume of humid air through the carbon filter. And since it’s more efficient in removing odours at lower humidity levels, I’m very happy with this. Intake air temp/humidity 20C/37%. Air temp/humidity inside the box after adding intake fan: 24C/55-60% day, 20C/60-65% night.
