Never used Big Bloom but Im my experience Tiger Bloom will put the straight burn on some nice plants. A lot of strains I grow are nitrogen sensitive and I have to completely cut them off of it later in flower. Im using an organic line now but I found the GH Flora series to work very well for me. You dont need as much as the bottles say but thats true for any fertilizer. Start with very low doses and see what works from there. Atleast with Gh you can keep the nitrogen separated. Just my two centsHello everyone, hope all is well with everyone and your plants of course too. Welp, I'm on a limited budget here...long story short- would one be wiser to buy Tiger Bloom or Big Bloom plant food? For flowering stage of course. I'm not sure which NPK value is better for indoor, first time grow? Anyways thanks everybody
