First Grow, Critical Purple Auto

Seeds came from my Brother, This is my first true attempt at growing this beautiful plant, Soaked seed with regular sink water placed in paper towel on a plate inside the tent with 12h lighting cycle. Day 3 noticed tail growth started in the morning, waited for a few hours and noticed the tail was about a 1/4 long maybe. Decided to plant because didn't want to take the chance to damage a long. Made soil checked soil natural PH with no adjustment reader shows roughly 6.5-6.8~. Poked whole trying to not going deeper then 1/4inch (think I might have went to deep). Once seed was in soil used made first watering cocktail of Fox Farm Grow big and Big Bloom and poured water around seedling trying to not over soak. I feel like I have done this step backwards. Placed in tent with 24 hour lighting until I noticed a sprout. It's approaching the 20h mark have not noticed anything trying to protrude through soil. I do quality control checks every 2-3h to maintain conditions in these ranges 65-75% humidity and 75-80F. Day 1 Seedling Noticed the seed starting push through the soil, light watering maybe 2 tablespoons worth of droplets twice today, lighting is set to a 20/4 I also turned off the red light and pushing blue and white, was reading that blue light helps with seedling growth. so giving it a shot track the results. environment remains the same as day 3. Day 2 Seedling. Grew fast pushed the seed cap off starting to open up continued to water increasing amount slowly Day 3 Seedling. opening up, nice little leaves however I did notice what looked liked to be browning or dry tips on both leaves very small tho going to keep an eye on this. Watered 1L added Silicic Acid extremely low amount probably did nothing or it will fry the plant we shall see, also add grow big and big bloom again lower then the recommended amount for 1L of water. I do not have a way to check my water PH levels so I am using Distilled water for now until my reader and PH up/down shows up however, I check soil PH levels are remaining the same 6.5-6.8~.. End of Day one of the little cotyledons is dangling and broken seedling is leaning I have the wire to try and help support hopefully this is not a problem
