Wedding Cake, first indoor grow

Started week 4, on Sunday, by watering 1/2 gallon per plant with just Big Bloom, Boomerang, and Kelp Me. The plants needed water but I didn't want to add all the nutrients to two waterings in a row. On Monday I changed the light timer to a 16/8 schedule getting ready for the change to flower. I left the 16/8 schedule for Tuesday and Wednesday on the timer. On Tuesday I pruned just a few of the smaller leaves at the bottoms of the plants that didn't get much light. On Wednesday I watered with 1/2 gallon per plant and the full schedule of nutrients. Also, I did foliar feeding with Flower Kiss right as the lights were about to go off. On Thursday I changed the timer to a 14/10 split and left it that way for Friday and Saturday as well. I had to leave for an emergency so I didn't get to flush on Saturday as I had planned. To hold the plants over since they were thirsty, I had a buddy water each plant just 1/4 gallon each. Once I got back into town on Sunday I did the flush, but that's now part of week 5. I got a new blower, 6" 440cfm, to use as an intake fan. The room has a vent for the central air that runs under the house. I disconnected the vent line under the house and installed a filter on the light. In the room, I'm installing the blower to pull the cooler air from under the house to help cool the room so the a/c doesn't have to run so much. Also got the temp and humidity controls to hook up the blower and the dehumidifier and humidifier too. The in-wall a/c unit has a "dry" setting and works a little like a dehumidifier which helps a lot when needed. Also, the roommate finally got everything out of the room, so now I've been able to open up the plastic wall, so cooler the area is much easier now that I have the full 12ft. x 11ft. room to use. Oh, and you'll notice the a/c is set at 73. That's because I keep it on the economy mode a lot and at that setting, it keeps the air between the lights and the plants (the area I check the temp at) at 78 degrees when the lights are on.
