I invested a decent amount of money in my setup. Unfortunately, I had to get local nutrients (second pic for ref). My girl is almost at week 3. She is pretty small. My soil is OMRI listed and has perfect PH but was way to strong for a seedling so I think that was the cause for the growth problem. If it matters I am growing one plant under a 400w HPS. Sea Soil, fan + carbon filter, PH meter, nutes. The nutrients I have is "Shultz All Purpose 10-15-10". I got the idea from the "Grow thread" below (I didn't follow this guide, only got nutrients from it because it was only local option). http://forum.grasscity.com/absolute-beginners/632534-budzills-cfl-grow-guide-complete-beginner.html My plant looks healthy, I have used no nutrients yet. Firstly, I have not the first clue when to use nutrients or how much. I know this is a very nubby question but any tips or point in the right direction would be great.
