Jack 47, UK grow

This is the first time I use seeds from Sweet Seeds, and so far are the best seeds I ever used. I soaked 2 seeds in water, then I put the seeds inside a paper towel and after 2 days I put the seeds in the soil. I'm using a mixture of coco and perlite, around 55% coco, 45% perlite. I only have one light turn on at the moment, at this stage is more than enough, in the future when the plants are big enough I will add the other light. When I put the seeds in the soil, I sprayed tap water on the top layer of soil, the first couple of days I didn't open the vents on the tent, and my exhaust fan was turned off as well. On day 4, with the vents open and the exhaust fan turned on I gave the first feeding. Around this time, I also turned on the oscillating fan slightly about the plants, to have some air movement around the plant, the fan is not pointing directly to the plants because at this time they are too fragile to withstand the power of the wind. DAY 4 - Nutes PH-5.89 Solution Temp-19.6 Watering Volume - 0.6L DAY 6 - Water PH - 6.08 Solution Temp - 18.8 Watering Volume - 1.5L At the moment Plant A is slightly bigger than Plant B. Plant A is about 7cm height, while plant B is about 6cm height. The leaves on Plant A are slightly more developed than Plant B as well. On the germination of the seeds is was clearly visible than one seed developed faster than the other one, I let the seeds stay one extra day on the paper towel because one of the seeds was not developed enough to be put in the soil.
