First Grow - Girl Scout Cookies

no pictures for a few weeks and now she is in Full Veg Mode. Just started the nutrients. I had a small issue figuring out the feeding and water schedules and the result was some droopy leaves (over watered). Also had a pest problem. I let the soil dry out as much as I could and then I added Neem Oil to my water and set a sticky trap. At first it appeared to work, then I still saw a few flying around. Next, I removed the top 2 inches of soil and replaced it with fresh soil and more need oil. I also put some peroxide in my drain pan and I never saw another one after that. Today I learned that I should prepare my soil BEFORE I put my seedling in there to ensure it will not have "pests". I see other mentioned specific soils while others were just treating the soil before they started their crops. I still have much to learn.
