Fpj mid and late flower
Hi
Can I use fpj banana flower all the way through? Or should I use something different mid and late flower for fpj?
thanks
Top answer
yes and no you could use the 1 type of Food (FPJ) all the way through if that's just what you had but its best to use 3 different types of food ....if the banana flower food is the Growth Food taken from the unflowered bud or growth tip that holds the growth hormones then you would also want to make both a Sour Food and a Sweet Food (FFJ) ... Sour Food is made from a single type of unripe fruit or flower of a plant and is used in the 2nd/mid stage/crossover period (the banana flower food could also be used in this stage i would think) .....Sweet Food (FFJ) is made from 3 or more ripe fruits and used in the 3rd-4th/late stage ....its important to switch to a Sweet Food during the 3rd stage this food adds brix, excites the microbial life in the soil to enhance fruiting/ripening and adds that extra bit of nutrients to the plant needed during that final stage to get the best end results
Happy Experimenting

Drake recommends changing the food as the plant changes stage. (Office Hours Ep. 16, 58:51) The food comes from growth tips, flowers, or fruit, depending on the stage. (Office Hours Aug 2025, 50:58)
- Early growth and structure: the chart uses FPJ at 8 mL per gallon, at 1:500. (Cho's Solutions, p. 12)
- Flower formation: use foods made from less ripe material, such as black locust flower, mulberry, grape or raspberry. They are more acidic because they are less ripe. (Cho, Recipe, p. 43)
- Fruit stage: the chart switches to FFJ at 8 mL per gallon. (Cho's Solutions, p. 12) Banana KNF food also works here as a fruit-stage food that adds potassium as flowers firm up. (Office Hours Ep. 11, 29:13)
- Late reproductive: use fruit enzymes made from ripe fruits, such as apple, peach or grape. (Cho, Recipe, p. 43) Cho says to apply ripe-fruit FPJ in the late reproductive period. (Cho, Recipe, p. 38)
The library does not give a week-by-week schedule for banana flower food alone.
