    When should I Fertilize my Seedlings?

    Mixes composed of perlite, vermiculite, and rockwool and other inert media should be treated with a mild application, 300-400ppm, of fertilizer prior to seed introduction to provide available nutrients and buffer the pH.

    Adding Hormex, Superthrive or some other auxin/vitamin based supplement will accelerate early plant development. It is not beneficial to apply additional fertilizer to seedlings in rockwool or other inert media until the first set of true leaves appear, at which point a 1/4 to 1/2 strength application is made.

    Excessively rich organic soil mixes are best avoided until the tender, young plants are well established. As such it is possible to feed young seedlings in soil with a 1/4 to 1/2 strength solution of fetiliser after two to three weeks or after the first set of true leaves appear but only if the soil is not super hot in terms of nutrients.

    Fertilise approx once every 2 weeks "Overfertilizing and overwatering kills more plants than the government does every year."....to quote BPP...........some growers will use more ferts and more frequently, but until you have a few grows under your belt.

    Re: When should I Fertilize my Seedlings?

    oops dang old threads... I would say get a 10-10-10- instead of that 20-10-10 and also if your soil pre-ferted don't bother with nutes for a few weeks.

    oh ya and redize, why couldn't you do that lol... just get rid of it if it pops male.

    Re: When should I Fertilize my Seedlings?

    depends on a bunch of factors - create a thread about getting ready to start your grow and give all the details like medium, nutrients, lighting, etc. soil, water quality, all that stuff is relevant. I'll be sure and help you out with that information!

    fox farm has info on their website.
