I was always able to avoid bottle feeding until a few weeks into flower by transplanting. I would start my seedlings or clones in either FF Light Warrior mixed with perlite or Happy Frog mixed with perlite in a solo cup. Once it was time to transplant I up pot to a 1 gallon with a mix of 1/3 Happy Frog 1/3 Ocean Forest and 1/3 perlite. When it out grows that pot it would go into its final pot, usually 5 or 7 gallon depending on the situation, with a mix of 2/3 Ocean Forest and 1/3 perlite. The constant introduction of fresh soil through transplanting means I never had to feed until week 3 or 4 of flower. Good luck!
