P vs K?

lapk78 · May 19, 2021

Hi all. We had a thrip infestation which interrupted the pollination cycle of my tomatoes and caused about 70% of my blossoms to fall off. I've got them under control now (using spinosad), but the damage has been done. I would like to encourage my plans to put on more flowers. The plants went into the ground mid-March, so are all somewhere between 3 ft and 6 ft tall currently. If I want to encourage flowers to grow, should I use a fertilizer that's higher in phosphorus (P) or potassium (K). I have primarily been using Texas Tomato Food this season, but I don't think it necessarily encourages more blossoms to form. I have already obtained Jack's Blossom Booster 10-30-20, but I have seen some posts saying that a higher K value will encourage more blossoms to form.

Any advice would be much appreciated. Thank you in advance.
