I am a newbie. These are 8 days old. My question is:
When do i start soaking the grow pot when i water and when do i start feeding nutes.
Please no condescending answers. I appreciate all the help I can get.

Thanks,

I'd wait a couple weeks before watering until drainage. I usually start feeding nutes when the plants have their 4th to 6th set of leaves. You are at 2 sets now,so in a couple weeks you should be fine to feed nutes(preferably not at full strength to start) and soak the entire pot until drainage at the same time.

If I vent my tent into the room and the humidity is high, do I have to worry about black mold forming in my house?

Usually company that sell fertilizers tell when you should start using them.
As a generic answer you should start when the plant gets tall 10/15 cm from soil but it may change as far as the concentration of nutrients into the soil you sure using is high.

I would suggest a read.

you should get the humidity down to 50/60 % rh and get a good ventilation.
Be aware to not push too much wind directly on plants as they may get a wind burn.
Also, into the tent, you want a good air exchange so the plants can breath, exactly as you do.
