My first grow under SANlight Q6W GEN2.1

The fourth week was a little bit adventurous.... As the plants started to flower, and the temperature outdoors started to warm up, the humidity raised up to 80%. Some of the leaves started to turn yellow, because it was too hot, and humid for them. First I was shocked, and I didn't know what to do. After some research I've ordered a dehumidifier, and I opened the tent and the windows into the growing room, because unfortunately right now that was the only way for me to circulate air in there... Everything else is okay, the plants drink twice as much water as they did in the beginning, I am giving nutrients only once a week, but I am hesitating on increasing the dosage. Or giving it twice. Update: The dehumidifier is a piece of crap, I have ordered an advanced one, which is able to extract 10 litres of water per day. It will arrive next week.
