Lots of updates - . I've added insulation and an air conditioner to my grow space and the temp is now stable throughout the day and night. I added a second 4x4 tent with a Grower's Choice ROI-E680S. 3 plants in each tent, the biggest of the 3 under the best light. Humidity is being controlled in both tents at 50% with InkBirds IHC-200s and humidifiers. I live in the desert and I'm not planning on needing a dehumidifier until dry time. I ran the ROI-E680S at 50% for the first few days of flower then upped it to 75%. The plants didn't catch on fire or anything. I'm not sure when to go to 100%. The other tent has two 125W Flexstar quantum boards. I moved those down from about 36 inches to 24. They've always been at 100%. Runoff TDS is decreasing as it should on most plants after several waterings with calmag added. I'm feeding every other watering with General Hydroponics FloraMicro/FloraGrow/FloraBloom. 1 ml/gal calmag every watering. No apparent PH problems except for #1, the biggest plant of the bunch. #1 had a low PH runoff of 5.8 after being watered with a 6.3 mixture. #2 and #3 both had runoff PH's of 6.3 and 6.4 from the same mixture. #1 is suffering from brown spots on some leaves covering roughly half the area of the plant. I wasn't sure what to do about #1's PH and the next batch of nutrient I mixed up landed at 6.7, so I re-watered #1 with the higher PH mixture. The new runoff for #1 was still at 5.8 and the runoff TDS decreased from 1530 to 1210. Switching to a dropper for PH up & down has been so much easier than attempting to use some fractional ml. I can dial in the PH I want from 1 gal to 4 gal by adding 5-20 drops, mixing, waiting 5 minutes, then testing. I would always overshoot before. #6 has always been small and seemed to lag behind the others. It still is. I think it may be actually be lettuce or something. I've noticed small white hairs sprouting from what I guess will be flower sites. I used a small microscope to take a zoomed in photo of one. I've decided I love all this and my least favorite part of it is dirt and the watering. After this grow I'm going to be full speed ahead on an RDWC setup.

@SavageKraken, thanks those were some fun photos lol

Looking slick puppers! Love it.

Looks great! Really nice pictures.
