Purple Lemonade Auto - (my second grow ever)

I decided to count day 4 after planting the seed as day 1 of my grow. I am still not sure what the official time is, it seems like everyone does it different. Day 1: Day 2: - Light still running at 40% with 23cm distance to the plant. that should roughly be around 200ppfd - Today I was adding the nematodes with normal tab water. About 200ml, of 350ml, that I should have used as the product tells, but I am a bit to scared to overwater the pot, as 200ml is definitely to much for the small plant and I don't know how much the fabric bucket can take, as it ist my first time using one of those instead of plastic. I spread the product on the whole pod evenly as I hope that this way no more fungus gnats will reproduce after the effect kicks in in 1-2 weeks. -Also I builded a light protection for my air intake to reduce light stress and repositioned my fan to be more modular as the plant grows.
