I still think 45% humidity is fine but Concauscion might have something in that your fan might be too close. Air flow is very important in an indoor grow for two reasons - one is that is moves air to get CO2 in and O2 out and helps control temp. The other is you want wind hitting your plants because this will strengthen the stems. Otherwise they will grow up, then fall over. The wind cause the stem to harden up to support the plants weight. When the weight becomes to great for a weak stem, the plant will fall over. It's hard to know what to do in a grow where you don't know ppm, but then you can just feed a little here and there, and see what happens.
when i drip i pump water with fert already. i currently have 1/3 strength of Grow Big and CalMag+. i usually measure with teaspoons but my ppm meter is being shipped from australia and i dont have the tracking number yet. and as for the air in my grow closet, i'm pretty sure i'm giving a good amount of airflow with a small fan blowing air on and around the plant.
