Interesting you've added a toothpick to the puck. Is that to hold the peat in place?

On humidity - This probably isn't a problem as you want low humidity for most indoor grows. The moisture in your soil will evaporate and get caught in a closed-in growspace. Lots of airflow is the answer to avoid moisture from collecting on and behind your walls where it will for mold that can actually put out a toxic gas, believe it or not. Adequate airflow is the biggest indoor grow problem. Everything else, from lights to ferts to soil, etc., is easy compared to making sure you have adequate airflow. And it's also the most overlooked issue. So I wouldn't worry about. If you bring in hot lights and use more soil and more water, you're going to see humidity rise.

For nutes, I usually recommend the Dynagro brand NPK ratio of 7-9-5. It's a one-part fert and has most or all of the nutes plants need. You shouldn't see any deficiencies with this fert. When they get to about 6 inches tall, transplant into 5 gallon buckets. This will take alot of soil but it you want them to produce, getting this right is important. 5 gallons of soil will be enough to last the duration of their lives. The Dynagro fert is easy to use and it doesn't take much - just 1/4 to 1/2 teaspoon per gallon of water is all it takes in a soil grow (directions are on the back). Just go easy on the fert when they're small and later switch to 1/2 as they grow. You probably don't need to fert every time you water. Let the soil dry out some before you water again as roots need some air in the soil and water forces air out. If you're going to add your own fert, I'd avoid using soils that are already heavy with fert, like Miracle Grow. I don't think you'll need the extra perlite and vermiculite. These aren't really necessary even though some people use them. Don't breathe vermiculite dust, it won't come out of your lungs.
