16set Mainline - First Ever Grow & Daily Progressives c_0

Day 0 Transfer day! So I ended up with 1 seed germinating and the other was a dud - the one that had a deformity on the "belly button". I prepared some 7.5ph water after a new calibration (about half cup) I tossed the top layers (about 6 to 10 inches deep) and weighed the pot to find that I had 15 lbs and 4oz. I didnt add any more. I inspected the rapid rooter pod of the new plant and seen the tap root peaking out from underneath. That was my cue to transplant now. Since it was only an inch big on the top I buried it at soil level. I then pour the half cup of 80F/7.5 ph water about 3 inches away from the new plant. I also placed a new dome with 3 vent holes over it. I then checked the lighting at the plant surface and found a 150 to 220 pppf spot to leave it. Lights are set to 18/6 schedule on a timer now. My tent has been running cool (73 to 74F) and my humidifier was delayed in shipping. So I placed a heater inside to bring the temp up and small cup of boiling water to increase humidity. And my inline vent is set to mid level at the bottom of the tent to help draw in heat from top. I also have a fan that blows down from the top Day 1 Started the day off with getting an exchange from the retailer that sold me a deformed seed. After that I inspected the new seed. No deformities in shape or color and no visible cracks, nice belly button, good veins, and a slight brown color with the tiger marks. (not sure if that matters, but noted it anyways.) Got my hot/cool humidifier today and set it to maintain about 75% humidity. It also helped bring the temp up in my tent. (still not over 78F but I like 76 better than 73) Seed warmer is maintaining 85 on the mat. I was going to soak the seed cap off the cotyledons with water and peroxide and then pick it off, but after one drop from a dropper, it simply fell off. Day 2 no need to really do anything today other than monitor the situation. So temp was about 76F and humidity about 80% in the tent. Seed starter day 1 showed temp at 85F and humidity also at 80% inside the covered dome. Noticed the sprout was collecting water on the leaves and cotyledons so I dabbed it off and made two more holes on the cover top. Continued to monitor throughout the day and that seemed to help. Also noticed that mycelium is growing on the soil top now. Day 3 Sprout showed more water collecting on the leaves, so I dabbed it off again and put another hole in the dome. Temp was 75F and 81%RH - turned humidifier down to achieve a RH between 70% and 80% Day 4 Sprout showed no signs of water collecting on leaves or cotyledons - The dirt looked dry but it felt wet when finger tested about 3 inches from the plant so I decided to let it be for today. 76% RH was better and where I plan to leave it for now. But the tent got a little warmer now that I have a heater inside, had to dial it back now as it read 84F I want to have about 78F +/- 2 Day 5 Sprout showed nice advance in visual size (just eyed) Dirt tested somewhat dry so I made some (1/2 cup total) de-chlorinated water at 7.4ph and peroxide. I finger tossed the top inch or two of soil and watered around base again with a flower watering can. I also sprayed the remaining top with a spray bottle with more 7.4/H2O2 water (no more than 1/8th cup) Temp was 78F and 78%RH Day 6 Sprout noticeably bigger today so I measured for future reference
