That's a judgement call you'll have to make. If it were my plant I would probably hit it with 3 tsp. Big Bloom, 1/2tsp Tiger Bloom, and 1/4 tsp Beastie Bloomz/ gal of water. However, remember, you'll need to flush all this stuff out at least 1 week if not 2(I prefer 2) before harvesting. It's really hard to make these decisions because of not knowing where the plant is in it's flowering stage. If they are in week 4 you can safely add the nutes for another 2-3 weeks. If they are in week 6 you are starting to push the line for not having enough time to flush all the nutes before harvest. This is assuming you have an 8 week flowering strain, which is hard to say because of not knowing the strain.:thumbsup:
