  3. Usually seedlings can go 3 weeks before needing to be fed. You'll want to start feeding soon with a fertilizer made for the growth stage. Not knowing if you have an indoor garden store near you, it's hard to suggest any one particular brand.

    If you do have an indoor garden store, you can't go wrong with the Fox Farms Trio Pack (Grow Big, Big Bloom, Tiger Bloom) Your hydro store can point you in the right direction.

    If you don't have an indoor garden store, you want to look for a fertilizer that has a higher first number (N=nitrogen) than the second two numbers(P=phosphorus/K=potassium) for growth, and for bloom, look for the second two numbers to be higher than the first.

    In the growth stage, plants need more nitrogen, while in flowering stage they require less nitrogen and more phosphorus and potassium. You also want to make sure whatever fertilizer you give them also has the right micro nutrients (calcium, magnesium, manganese, boron, selenium, iron, sulfur, zinc and copper).

    Once you choose a fertilizer. start off slow with 1/4 strength of recommended dose, and gradually work up to full strength. Your plants will tell you if they need the dosage upped by their color......if they start to look lime/light green, up the dose. Good luck on your grow and have fun.
