So I am in my first week of flower stage and I'm not sure totally sure what to use for nutes from here. When I flipped them about 5 days ago I gave them 2 tbsp of foxfarm big bloom per gallon of water. I have 3 plants, each in 3 gallon plants. I water each with 1 gallon of water and it seems to be the right amount of water each time. Today I just watered them with ph water, no nutes. They are in foxfarm ocean soil also. I have FF grow big, big bloom, and tiger bloom. What should I use from now till harvest? Can I combine the nutes together? Should I?
