Blue Cheese, UK Grow

I introduced an oscillating fan this week, I was able to feed the plant 1 time, still not the ideal amount, the soil is taking too long to dry. I feel that the main problem that I have now is the room temperature, during the day the maximum temperature is 21, and during the night it can go down to 16. I would love to have these temperatures at the end of flower, not at this time. Because I'm having problems with the soil not drying fast enough, I've been skipping on giving plain water to the plan, I've been giving nutrients all the feeds, I usually alternate between nutrients and plain water. The plant does not seem affected by this. I feel that the plant is picking up, and is growing faster by the day. DAY 27 - Nutes PH - 6 PPM- 706 Solution Temp - 22 Watering Volume - 1.5L
