LED. Airpots. Soil. LOTS of Q's!

Hey yall. So this is my 2nd grow, but first with FEM seeds and Airpots. My first grow went well in soil and I used mystery seeds so I didn't mind making mistakes and I learned a heck of a lot. This is my FIRST grow with Airpots+LED so I want to do my best. So here is what i'm working with....

2- Fem-Blue Widow (White Widow X Blueberry)
2- 3gal Airpots
Soil: FoxFarm OceanForest + Perlite 30:70
LED: 357magnum
Room: 3"X 3"

I've already germed the seeds and placed them in plastic cups. They are 1 week old. I'm going to wait until they're approx 3 nodes high before I transplant them to their new homes unless anyone thinks I should do it sooner?? I'm also a little concerned with them temps it's a steady 83.6 in the room, 81.6 in the soil with 70% RH.
Will that slow growth for seedlings?

Any advice from people that are using Airpots, soil, and LED would be greatly appreciated!!!

That LED is a little small for a 3x3 area. So dont let your plants get to big before you flip
Those environmental parameters are perfect for seeds.
3 nodes is about right for transplant, I might even wait a bit beyond that.

What nutrients you plan on using?

Yeahh I hear ya, that's why i'm only doing 2 plants at a time. I will use GH Bloom and Micro. Not sure how long it'll be until I need them, all depends on how fast they grow once transplanted. Usually stick with PH'd water first 2 months.
