Update 5-2-20Too Hot, Too Humid!
I can feel our short northern spring is turning into a hot and humid summer quicker than I anticipated.
I keep my tiny little humidifier on full blast or "level 2" with the closet completely closed and temps reached towards 90 F and humidity was going past 80%. I also have to manually turn the humidifier down to "level 1" as the plants go to sleep, then back to level 2 when they wake up, thanks to VPD at work. I realized that this is too hot and too humid so I came up with a solution. open my closet and set another humidifier in my room on full blast. Also, I close the room door to prevent humidity from escaping. Now I walk in the room and I'm suddenly in the Bahamas.
Here are some rough temp data from my new plan. Thought about screenshotting my Govee app chart that monitors my sensor but there's nothing interesting about those lines.
Night environment 6 hrs(door always closed to prevent light pollution): RH: 50-60 Temp: 70-75 F
Lights on 18 hrs: RH: 40-60 Temp: 80-85
Compared with my previous numbers, this is quite the improvement. I've always been happy with my nighttime environment, except for one thing, air.
And I don't mean air circulation, specifically CO2. when the closet is closed it hardly gets any outside ventilation besides the tiny crack between carpet and door. Even with the air filter going on Med I sometimes open the closet during lights on and the air is stale and heavy. I've noticed powdery mildew on my leaves due to the high humidity so something had to change. leaving the closet door open during lights on should solve both of these problems and allow the plants to breathe better.
Double up
Here's something that adds to my problem a bit more, but it will definitely be worth it. I realized that even the 2000w LED wasn't enough for this closet with the number of plants I have in it if I run it just on VEG.
I harvested my basil the other day to make room for my two hydro totes in the other closet. I thought I might as well move my 600w LED into the veg closet. Now I have them both running just VEG. I love this
Burning Babies
You guys were right about the N Toxicity instead of Deficiency. She's clawed out and the lower leaves are slowly dying and they're moving up the plant. The plants still have a little weight in them, but they're mostly dry. I think I'll feed them all when they wake up, 2 mixtures, one for the 1w CBD, and one for the 5w randoms. Then I will hopefully have all of my soil plants on the same feeding schedule.
I'm thinking about buying mylar for my closets to additionally help with light. Since I don't have a traditional tent, I just have white walls. Let me know what you guys think of this Vivosun mylar roll on amazon. 25 ft for $21 or 100 ft for $31.
Virus struggles
With my 2 jobs as a Retail Merchandiser, I am deemed essential and my work is still needed. I am thankful to still have both of my jobs when so many are out of work. However, retailers like Best Buy have completely cut off third party work and so went a huge chunk of my paycheck. To make a long story short, I'm broke and my clay pebble order on amazon got declined and so the delivery date got pushed back. My DWC babies will have to keep bunking together until 5-8, hopefully, sooner.
I don't have many pictures to post, basically, everything from the last update has just progressed a bit. including N toxicity.As always Grow On Blaze On
No need to worry about co2 at night. They use co2 for photosynthesis so they don’t really use it at night. The roots however take in O2 at night, Also at night vpd doesn’t really matter but get the humidity low at night so you don’t run into any dew situations. It’s the worst. As the temp lowers the ability for the air to hold water decreases and begins to fall out. I’d 100% suggest a fan running 24/7 in there. If not there will actually be a vapor barrier formed under the leaves which can someone “choke” them up. Other words keep up the work man. If you run into problems it just means you get to learn something new and each time makes you a better grower.
The toxicity seems to be slowing down, it's taking its time to shrivel every leaf on its way up and it hasn't reached the first node yet, so that's good news. It's in rough shape, I hope it can recover. 
close enough. I was right the first time, I should have just switched over the meter
