ICE 3rd grow

I there iv not used your range of nutrient for a while, have you got the right ratios of nitrogen phosphorus potassium Calcium and magnesium. Check out a feed schedule for your product and make sure your giving enough Calcium ànd magnesium. If a max dose is 2ml/L you shouldn't need to go above that.

Hey man. I think u need to flush the soil first and check the PH. This can be a reaction to the overfeeding with Green Sensation and PK 13 14. So overfeeding or PH out of range I think. It won't be mold cause u say the plant has a good airflow and that's the major killer for mold 😉 a bit higher humidity alone won't be enough then to start mold. Just one good flush and a week no nutrients won't do any harm and that will solve it imo Greetings
