Mkrono's First indoor grow

Hey people, this is my first grow ever and Im glad to be part of this community as I know im going to have a ton of questions as time goes on. Lets get started.

Tent: 4x4
Light: 600w mh/hps
Inline Fan: Vivosun 6" 390cfm
Filter: Vivosun 6" Carbon filter
Pots: 5gal
Medium: Sunshine Mix #4 with Frazz n' Dazzle amendments.
Nutes: TBD

Seeds:
2x Blue Dream
1x Girl Scout Cookies

Im on day 5 since germination and getting the seeds into solo cups. Currently fighting low humidity issues and but the temps are manageable. The smaller GSC is day or so behind the other two and I think I may have over watered it a bit but still alright. Here are some picture in those last few days. Thanks for checking it out.

I havent used the dry amendments yet but will top dress the solo probably in the next watering and will be mixing it with the sunshine mix in the 5gal. I have no idea what nutues il be using but figured I have a bit of time to decide.

I'll follow ya

Update Time!

Week later they seem to be going strong. Light is sitting at 28" no stretching from what I can tell. I bought a small cool mist humidifier and its struggling a bit with the light being on so not sure im keeping it. I have been spraying the soil typically every other day when the soil feel dry below. What do you guys think? Anything spotted that I dont realize?
