Green Crack #2

Struggling to get the pH down in my soil. Feed less General this week as some plants showing dark green leaves and don't want too much Nitrogen during flowing. Was having issues with humidifier filling up and cutting off letting the humidity rise for some time. I ended up clamping a hole onto the outlet of the dehumidifier and putting it on a bucket, the holes leaves the tent and fill up a bucket. I also now have my extractor fan on 24/7, up until now I have only had it on to cool down the tent in the past. Not sure if this is bad practice but didn't seem to have an negative effects. Pistils changing colour to orange and trichomes are turning milky, still a bit to go for me.
