When to start nutes in Promix HP with Advanced Nutrients?

Hi, I use pro-mix and it works well. The trick is not to overwater it. Start germination in a paper towel once it is ready, grab the pro-mix and mix it with little water( when you squees it no water will come out.) plant the seedling. once the seedling is stablished the next Day or 2 day, add water until it comes out at the bottom of the pot and don't water until the grow medium is dry and repeat until 2nd week. You can foliage feed the plant (low % of nutes) at the 2nd week of grow. Third week star feeding the amount advance nutrients recommends for your plant. Happy grow!!!!
