First ever grow

For my first ever grow i bought some white widow autoflower seeds from RQS. I bought the autoflower starter kit from RQS with the propagator. Because i bought some other stuff as well i ended up with a whole bunch of free seeds. thats why i decided to do a little experimentation and used a few different approaches on these seeds before i start messing around with the seeds that i actually paid money for. I planted the 3 white widow autos that came with the starter kit obviously i planted this in the propagator that came with this starter kit. And i also planted 1 Tripple G seed directly in the pot. Plant 1 WW: germinated in the propagator, then moved it to a 14 liter pot as soon as it sprouted 23-01. Put it in Plagron Batmix. Did not make any changes to the soil. Plant 2 WW: germinated in the propagator, then moved it to a 14 liter pot as soon as it sprouted on 24-01. Used the same Plagron Batmix, but with a little twist. In the midle of the pot ive put about 0,5 liter of seeding ground in which i transplanted the plant after sprouting. Plant 3 WW: didnt make it unfortunatly. Not sure what went wrong there, i think maybe it got too wet or something. there were signs of a root forming, but no sprout came up. Plant 4 Tripple G: Germinated it directly in the 14 liter pot on 23-01. Like with plant 2 i filled the 14 liter pot with plagron batmix, and in the middle put about 0,5l of seeding soil. and put the seed in there with nothing more then just a splash of water for humidity. it sprouted on 27-01. For this diary i've decided to time it according to plant 1 and when it was first seeded/sprouted. I think ive made it through the first week quite well. Not too many things going wrong besides the one seed not comming out. Tried not to mess with it too much, and was very careful with giving water. its some big pots for some small plants so i kept it to a max of 50 ml per watering using an hand sprayer. I did flush the soil beforehand to wash of excess nutrients so this is also cause to be careful with the water. Keeping the water PH level at 6,8 for the forseeable future.
