Yes the 1st 4 weeks use only only grow and big bloom. Make sure you note that Bloom is a table spoon and not a teaspoon like grow and tiger bloom. I must have been baked cuz I didnt even look at it again untill 3 or 4 weeks in .

Another thing you will use grow in weeks 7 & 8 into flower.

Hope this clears it up for you.
bigworm1922 Reviewed by bigworm1922 on . Fox Farm question I am using Fox Farm Grow Big, Tiger Bloom and Big Bloom and would like to know about the feeding schedule. I have the print out and looked it over. It says that I should be using Grow Big and Big Bloom during Veg, is this correct? I guess by this Tiger Bloom is just for Flowering? Can anyone confirm this or let me know how you use these three if you use them. Soil grow. 4 weeks old. Thank you very much. Rating: 5
