Yellow leaves on the bottom of bush bean plants
Comments (14)Used at low rates, the 5-10-5 probably won't hurt anything, but it supplies about 12x more P than your plant needs in relation to it's N needs. Since N is the must used element, other nutrients are usually measured as a function of N. While going about the chore of growing, plants use about 6X more N than P, so I can't think of any container culture application where it would be better to use a fertilizer that supplies more P than N. That said, it's not going to kill your plants or cause great harm; it's just that there are better options. If you were referring to the 24-8-16 as a high N fertilizer ..... it really isn't. Remember, the % numbers mean nothing individually. If there was a fertilizer that was 48-16-32, it's not considered a high N fertilizer any more than 9-3-6. Yes, it has more N by weight than the 9-3-6, but both are 3:1:2 ratio fertilizers and contain the same amount of N. How this works: The instructions for mixing will direct you to use only about 1/5 the amount of the more concentrated 48-16-32 as the 9-3-6; so in the end, you're supplying the same strength solution, even though 1 fertilizer id many times 'stronger' than the other. The 3:1:2 ratio fertilizers work so well; because there is little excess in the soil. Let's think about what happens when you use your 5-10-5, with 12x more P than necessary. Let's say your plants are looking a little yellow & need fertilizer. You fertilize & all starts to look well, but soon, your plants are running out of N and yellowing again. Since there is still lots of P left in the soil, you fertilize. This supplies a little N (in relation to P) but it alsu supplies another BIG dose of excess P. Now you have LOTS more P in the soil than necessary. P raises pH AND competes with Fe (iron) and other micro-nutrients, the symptoms of which includes the yellowing that comes with deficiencies. As you add more fertilizer in the hope that the yellowing will be reversed, it gets worse instead. When you use a 3:1:2 ratio, the plant uses the nutrients evenly, so they are all becoming deficient at the same time. When you fertilize, you're not increasing a notable excess on ANY element, which is not the case as when using high-P formulations. If you have a plant that needs to have its vegetative growth slowed, simply switch to a 1:1:1 fertilizer or alternate its use the same 3:1:2 ratio you're using. You can also use 3:1:2 ratio fertilizers at low doses (to restrict N) and supplement the K (many use Pro-TeKt 0-0-3 for this). A summary: I use 3:1:2 ratio soluble fertilizers on EVERYTHING, unless I am intentionally trying to stress the plant by limiting an element (usually N), and I never intentionally apply a fertilizer that will supply an excess of one or more elements in relation to the other essential elements. Excesses are as bad as or sometimes worse than deficiencies. (Dr C Whitcomb et al) Al...See MoreLeaves drying up on Bush Beans?
Comments (2)Several possible causes - excess heat, diseases like bean rust, injury, pests, inconsistent watering, nutrient over-dose, etc. The list goes on and on. So just guessing and given your location and that they are in containers (which is unusual), if there is no sign of pests then the odds are it is a watering and heat issue.

Comments (4)Krex, I'm so sorry to have missed this post until now! This forum can be a bit slow, but the folks here are very good. I think you've probably done just fine. I would not remove the plants. I'm not positive about some of that "rust." But the leaf farthest to the right has leaf miner damage. Those little bugs live inside the leaf. Removal of the leaf and destroying it away from the garden is generally the best thing to do. The color of the leaves, with the exception of that one, is good. Rust, actually is the name of a condition, and this may be what your plants have. I haven't seen it for quite some time. But I suppose it is fairly common in some places. Take a look at the link below. It deals with Rust. Also, as I write, I am remembering something my father taught me when I was little. I do it to this day, though I seldom think about it. He always told me not to touch or even walk through our bean patch while the dew was on the leaves. Weeding while the leaves were damp was taboo. I believe the reason he gave me was that it could cause rust. I grew up in NJ in a humid climate. Where do you live? What is your climate. Perhaps this might give us a better idea as to the cause of this problem. George Tahlequah, OK Here is a link that might be useful: Rust on Bean leaves...See MoreYellow leaves on bush bean
