umm for budding you should get tiger bloom but for wutever veg stage nurtients you get dont start using it until the plants about a month old its not good for it
Wait for the seedling to reach 3-4 weeks old. Around this time you should start with a fertilizer with a higher N than P and K. suck as 20-10-10. For the flowering stage you would want a higher P ratio such as 10-20-10. Good Luck
