Before you do any planting tho...
1) What kind of soil are you using? (Brand? Premix or your own mixture? Fertility?)
2) Have you added any blood meal, bone meal, earthworm castings, ... to the soil?
3) What nutrient line do you plan to use throughout the grow?
Most soils have more than enough nutrients for your lil babies to last 2-3 weeks, some a month, so be careful not to get ahead of yourself and start feeding too early. Gradual progression in feeding as you approach maturity is very important! Look into purchasing a PPM/PH/EC testing unit, if you do not already have one. This will allow you to control your feeding solutions to the T and know exactly what levels you are preparing, so that you can make the necessary adjustments.
Hope all this helps, and look forward to hearing more about your prep work!
