1600 Watt Grow (First Round) Day 1 Flower

Just got new lights used to have a 400 for my 1st grow but decided to upgrade to a 1k and 600 watt. Just ended up throwing a bunch of different strains i have in the room to fill it up next time around will be more organized. Any advice or suggestions are appreciated, the room also has C02 enrichment. Also i have a question, im using outside air to cool the lights while keeping the room sealed; the air outside is so cold that when its going through the ducting condensation makes the ducting drip a lot of water leaving little puddles in my grow room is there any way to fix this?

yeah, i would pull the ambient air from inside the house to cool your light instead of pulling from outside, obviously the hot light and cold air from outside is causing the condensation..

flipped the fan and things running much smoother in the room plants have grown a bit. they sucking up 10 gallons every 4 days thats a lot of nutrients. right now giving them some bud factor x i got for free and some cal mag. My white widow seedling in the waterfarm doesnt seem to be recovering very well, there was a ph issue that i didnt notice until a few days after and growth has been stunted i think im going to start a new seed and try again, im planning on scrogging the seed so it can have the 600 watt to itself gonna try to get a lb from it with co2 enrichment seems possible. update picture of grow room and seedling
