First grow. Hope all goes well. All comments very welcome

Newbee here with my first grow. Although this is my first post, I've spent countless hours reading posts on this site and have learned ALOT! OK, Here goes. My set up is:

4X4X6.5 foot Grow Lab tent
2 Global Greenhouse 24 inch 4 lamp T5s (only one used initially) for seedlings and veg
1 1000W Global Greenhouse ballast/HPS bulb, air cooled reflector (to be used for flowering)
Sentinel CHHC-4 unit to control environment
CO2 supplemenation (20 lb cylinder with solenoid valve)
Aurora Innovations Roots Organic growth medium
Full line of House and Garden nutrients

3 Barneys Farm Violator Kush (fem)
3 Barneys Farm LSD (fem)
3 Dutch Passion White Widow (fem)
3 Reserva Pravada OG Kush #18 (fem)

seeds were germinated in 18 ounce party cups. All times are from when the sprouts broke the soil surface. One LSD and 2 Violator Kush did not sprout.
2 additional Violator Kush seeds planted 1 week after initial seed planting (using the wet paper towel method ths time). They popped and were planted in soil in 2 days.

This grow is 1) for personal use only, and 2) a "science experiment" to see if I can actually do this. Because of space constraints, my plan is to hopefully end up transplanting one of each strain plus two of the most healthy other plants into 3 gallon containers when the time is right. The rest will have to be sacrificed

The first set of photos are at day 4. Front plant is WW and the one behind it is OG Kush #18. Only pH adjusted water (6.4) and Root Excelurator added. Daytime temps 85 degrees F, nighttime temps 75 degrees, RH at 70% day and night, and CO2 at 1500 ppm (day only). 16/8 light schedule

Good luck on your first grow. + rep for giving it a try.
