First day of week 5. Some light brown spots appeared today on the fan leaves of D1. Will fill some buckets tonight to do a full reservoir change tomorrow. New growth at least looks healthy.
I'm struggling with a low humidity situation at the moment. Temp inside the tent is at 26°C humidity is at 35% . Outside the tent it's 20°C with 45% humidity. I've choked off the exhaust to reduce the air exchange rate, have a gallon of water in a bucket with air stone in it, I spray 2 times at least a day (which may have caused the brown spots today maybe?), And have another small container with water in it. But now I really just need to go buy a humidifier.
