Blueberry Auto- Zamnesia Seeds

Growing three Blueberry Autos from Zamnesia. I have 2 fabric pots of 15L and 11L to experiment and see what differences the pot sizes make. I germinated the first 2 roughly a day apart and decided to germinate the last one just for fun. Because the 3rd one also germinated I rushed to get another pot, a 9L plastic pot, which isn't ideal but will be interesting to watch. The youngest plant is 5 days old and the other two plants are 9 and 10 days old. I positioned the light 35cm above the plants at 50% light intensity as is recommended by Fecida putting the maximum PPFD (at the center of the light) at 480 (as Fecida claims the light to have a PPFD of 960 at 35cm when at 100% intensity). In addition, cut plastic bottles in half and sprayed them with water to serve as humidity domes for all three seedlings, however now I only use a humidity dome for the 5 day old seedling. The second oldest seedling in the 11L fabric pot is showing signs of stress, with 2 small yellow spots on the leaves and a noticeable leaf curl upwards. As it is my first grow I am not sure yet what I have done wrong, and I will watch over the next days to rule out overwatering, excess nutrients, or too much wind (from my garden highpro 15cm fan). I mixed in a 150g bag of Monster Bud Mix from Zamnesia (the pellets) into my initial 15L and 11L fabric pots. My final plastic pot does not have added nutrients as I did not expect to have a 3rd seedling to grow. I have not fed the plants any additional nutrients yet but I am planning on starting to mix in the Bionova X-cel stimulator from the Zamnesia Monster Bud Boost Pack next week when the plants are bigger. Thanks for reading and happy growing to all! :>]
