First Grow: Nine Autos in 5 x 5

05/05/21: Planted 9 seeds into Jiffy Pellets after submerging in tap water for 5 hrs. Buffered 9 pots of coco for 1.5x Calmag dose @ 200-220 ppm 06/05/21: No Changes but too impatient in checking the humidity dome every hour 07/05/21: One of the seeds have broken the surface, moved all under lights. Mars Hydro TSL 200 @ 100 Intensity @ 30" 08/05/21: All seeds have sprouted, half still had the casing so I manually removed these along with any excess film stopping the cotyledon from opening up. Stems looking bendy possibly from being left in the dome @ 85+ RH too long. Things that went wrong today: - They all grew out of the jiffy pellets before the first leaves have fully formed. I had to set everything up in a rush to put the exposed roots in a dark place. Back is now sore -AFter transplanting, I watered all plants with 4 litres each of half strength nutes and calmag, and set the lights 30" above canopy. -The aircon is on all day but the temp inside the tent is 30 C and humidity fluctuates between 40 and 60. -I will set up an autowatering system soon using drip halos but boy is handwatering a pain. -Need to look into more efficient draining solutions as well. 9/05/21: I may have overwated my plants. Even tho I have 50/50 perlite, I accidentally soaked the jiffy pellets and the plants while hand watering. -Expecting for all plants to die as to not keep my hopes up -Put dome back on the struggling seedlings to keep humidity up 10/05/21: 7/9 plants looking healthy. The other two are recoverign and showing signs of growth but significantly slower.Dome seems to be working. -Water twice @ 200 ppm. 2L per 5 gallon pot. 11/05/21: Not much changes, Stunted plant is trying its best to recover. Looking unlikely though, it's already a few days behind the largest plant. -WAter once @ 270 ppm 5.8 ph 3 L per pot. 13/05/21: Worried about heat in grow tent lingering around 30-32 C,
