Pineapple(Skunk, Express)

Update 1/19 (day 9): * The plants are maturing a bit more so I increased the light output back up to 100% (up from 75% at the end of last week). I bought a light meter and they are getting about 48.6K LUX at the top of the plants (I checked each plant individually and they are getting the same amount of light). I have mostly been not using the side lighting during veg. * Still riding the last nutrient swap at the end of last week (with week 2 ratios) at 60% dilution and in a few days I will get them closer to 80%. * Root development is looking really good for all of them. The biggest plant is getting its second full set of leaves and the others are about 1 stage behind at the moment. * Humidity has been challenging with winter in full force. I have the humidifier blasting right outside the box but it can barely crack 50% at the moment. Update 1/21 (day 11): * The oldest plant started to branch out before I wanted it to so I trimmed off all the small branches yesterday. It didn't seem affected and has been growing strong since. * Starting to see more vigorous growth. * Exchanged the nutrient water after a quick flush with only PH'd water. Now nutrients are at about 73% strength and 740 PPM with a 230 PPM base, the highest PPM I plan to go during veg. Update 1/23 (day 13): * Discovered that water was increasing in PH to the point I couldn't control it. After some troubleshooting I determined that the CO2 bag was working, and working well. My DWC pump was in the box and pumping CO2 into the water which increased the acidity every day. I have moved the pump to the outside of the box so it is pumping fresh air into the water now. * Had to replace the water because of the CO2 incident, the water became very cloudy and didn't look right. At about the same strength level as before for nutrients, sitting currently at about 75% strength. * The Pineapple Skunk is directly next to the CO2 bag and it seems to be working because it is really starting to grow vigorous and is a darker green than the other two. Noticeable differences that correlated with when the water was becoming acidic. I need to buy a CO2 monitor but haven't felt like dropping $100 for it.
