First grow RQS Special Kush #1

Hi all, this is my first grow ever, so I am using this diary to keep track and maybe get some tips and tricks along the way from the more experienced growers. Planted on 22nd September. BioTabs Bactrex in the water used to inflate Jiffy, also spread a little bit of BioTabs Mycotrex in the planting hole. Kept the humidity dome with open holes and slightly tilted so there was fresh air. Humidity ranged from 65 to 80, but mostly it was kept in the 72-77 range. Temperatures were around 21 to 24 C with complete darkness. Extractor fan is kept working all the time at around 40% capacity, just to bring fresh air in. On day 3 after planting they were getting a little bit dry, so I watered them with 7-8 ml of spring water each. On day 5 - 2 of them showed up above the soil, but the first one still had the seed shell stuck to it, I applied a bit of water and it came off by itself. I suspect it's because I might have planted it too shallow. It looked a little bit stretched, but should be all right. I've turned on the lights, it's a Mars Hydro TS1000, currently 70cm away from the plants at about 35% intensity, LUX meter is showing roughly 5k LUX. On the next day I will have them at the same height, but at 50% intensity at 9k LUX. On the next morning the 3rd seedling showed though and looked fine. I will keep them in the Jiffy pellets for maybe 1 or 2 days more, then I am planning on transplanting them to 8L pots using BioBizz LightMix and the BioTabs feeding schedule. Still haven't decided if I should wait a week or so before adding the BioTab slow release and the Orgatrex. I was planning on just adding Startrex + Bactrex + Mycotrex, but waiting on the BioTab and Orgatrex for like a week so I don't give it too much nutrition - ideas are welcome here.
