| I transplanted a hot pepper plant with no buds into a hydroponics system about 3 weeks ago and this week, it started growing like crazy, putting out small new leaves and new buds almost every night. However, the buds and flowers have begun to drop. There was heavy rain over the past 2 days, and I am hoping that was the cause. I don't think there is too much nitrogen because there are no dark green leaves - the new growth is a light green color.
I am wondering if the problem is because I keep the pepper in the shade (just for now because the nutrient heats up too much in the sun), or that I am using a grow nutrient (dyna-gro 7-9-5), or something else entirely? If I should switch to a bloom nutrient, which do you recommend? |

| Obviously, the plants can't support the buds and the blooms and drop them in order to survive. I suggest you switch nutrients. Best for peppers = N: 208 ppm P: 40 ppm K: 340 ppm (peppers love potassium!) Ca: 170 ppm Mg: 50 ppm S: 40 ppm Can't recommend a make/brand, 'cause I live in Africa where such things are almost unknown. |

| So what percentages in the nutrients would that translate to (ie 10-10-10)? I have never seen bloom nutrients with that much potassium. It is always highest in phosphorous, potassium and then almost no nitrogen. Has anyone used advanced hydroponics 3 part nutrient or ionic 3 part? |

| I think you could get a long way by just adding KNO3 (Potassium Nitrate), which should be readily available. Surely you can work out the quantities . . . it's basic chemistry. |

| Willard, I've read your flower drop probable causes in other threads, but looking at them, the only one I might have is too much nitrogen. 1. Day temp 80-90 So I'm not sure what my problem is, unless it's too much nitrogen. I'm planning on getting some bloom nutrient soon to try. |

| Could it be calcium deficiency? My nutrients are 2% calcium. |

| Too much nitrogen in the nutrient mix. Try feeding them just water for a week or two. Maybe just try this for a couple plants, so you don't risk your entire crop. I've grown peppers and once that bloom sets, it's all about reproduction and the need for more vegetation is really low on the to-do list. God bless. :O) |

| Well, it stopped dropping buds and now looks like it is about to flower. It's still growing crazy fast though. I never got around to switching to a bloom nutrient, I just dropped my grow nutrient to 1/2 recommended concentration. |
