Indoor Multi-strain Madness!

Lots happened this week! I got a new tent for free from a friend he had never even opened! He didn't remember the size - getting it out of the bag it was 5x5!!! After a tough setup squeezing it in my furnace room corner on my own I got it rocking and the girls are now VERY comfortable. I gave them all a decent haircut right before switching last Sunday to 12/12 and took 4 clones off of the blue dream for fun. They have since gone into the previously used 3x3 under my old 300w blurple. 2 of them are looking pretty good with 2 sadder looking ones. We'll see how they do, I'm thinking of dropping a few more seeds to join them and veg in the 3x3 until the 5x5 girls are harvested. Any and all problems have been sorted out! The leaves are all now a vibrant green, the odd little spot lower down but overall they look great. They are all still quite short with not a whole lot of vertical growth yet so I've only slowly lowered my light, now sitting at 22-24" from the canopy in hopes to encourage some good flowering stretch through next week. The runty blue dream is still under 10" tall, very strange plant. Feedings have moved up to every other day, the odd every third day if I;m busy but they are pretty dry by then. I've increased the PPM by 100 over the week and transitioned the grow down and the bloom up. Environment is getting a little tough to manage now that they are in a big space but I think they are fine as is, humidity is a little low but it has been their whole life. I'm buying a whole house humidifier as I hate the dry winter anyway so once I get that unit installed it should come up 5-10% everywhere. I'm 19 celsius lights off, 22 lights on and a steady 40% RH give or take a few points either way this week. I noticed a couple tiny bugs scooting around so I added some sticky traps on the top of the medium and a 12" fan oscillating over the tops of the pots to keep them from laying any eggs and getting any ideas about setting up shop! I tossed in a few close ups after a week of 12/12, the pistils are starting to emerge from the nodes and stretch out and the top of the growth sites seem to be concentrating and stacking up very tight growth. Hopefully see some flower development next week! Thanks to everyone who has helped me thus far!
