Greetings,
Less is always more on when it comes to nutrients. When starting in bigger containers one must be careful to not overwater. I have never tried using the pellets, I just soak in water, then plant 1/4-1/8 of an inch deep in soil, cover and keep moist with spray bottle. I start photos in solo cups, autos in 5 gallon minimum, run indoors for a month and throw outside, transplanting them into forever homes.
Here’s my last auto journal, I ended up transplanting some into bigger containers than I had originally planned. I add extra peat in my soil to make it less nitrogen hot as seedlings are sensitive to it. The earliest I fertilize beyond what’s in the soil is 4-6 weeks old. The plants need to develop root system to grow more than they need to be fertilized.
Thanks @Not2SureYet
