chasv77answered grow question 4 years ago I run FFOF in all my grows, and I'll tell you that you do not need any nutes for at least 30-45 days.
Unless you have a strain that is proven to drink up nutes, or your auto is fast to flower, then you may never need to feed the veg formula.
I do not follow the feeding schedule exactly, as far as the up/down strengths of the nutes, during the flower duration.
I never exceed 50% strength, after start of feeding.
As well, because FFOF is hot, I cut the soil 3:1 using their Light Warrior mix. This helps buffer the soil hotness, while adding more perlite to keep the soil from compacting during the entire grow.
Good growing!
