Tomato plant leaves turning yellow with brown spots
Comments (13)The label should tell you if you need to wait a certain number of days to harvest. IIRC, Daconil has no wait time to harvest when used on tomatoes. It would be almost impossible to avoid spraying your fruit if you're spraying correctly. Remember that you have to spray all stems, foliage (both top and underside), and preferably also all developing fruit as well. If you can do that and avoid getting anything on mature fruit, you are very talented....See Morewhy did one of my leaves turn yellow and die on my dumb cane?
Comments (8)New growth isn't a clear indication that the plant is growing. True growth is measured by a plant's increase in dry weight; so, if a plant is shedding a leaf and growing a leaf, it's roughly in a static state, which is not a good place for a plant to be. I'm not necessarily saying the leaf ISN'T being shed as a result of normal senescence, only that new growth might not indicate an o/a increase in mass. There is no better fertilizer program than one you can control to the degree you know exactly what nutrients your plant is getting, how much of each, and when nutrients will be available for uptake. There is an ideal level of nutrients in the soil and an ideal fractional amount of each in comparison to each and all of the others. Most plants use about 10X as much N as P, and about 3/5 as much K as N. The rest of the nutrients also have an ideal level determined by a function of N levels and the overall level of total dissolved solids (TDS) in the soil solution. Adding tonics, miracle concoctions, or supplements targeting an increase in 1 or 2 nutrients w/o good reason or a strong likelihood what you are doing is going to correct a deficiency, is far more likely to result in limitations than benefits.

Comments (3)It is possible you have Early Blight. Mine do the same thing. They will be fine until the first full day of high heat and humidity then it just explodes. The first thing to do is get all the bottom leaves trimmed off - I've read that it is fine to take everything off at least the first foot of your plants and even up to 18". Get them in the trash then wash your shears and gloves with bleach. This will help stop the spread. Copper fungicide or Daconil sprays, or Epsom Salt drenches are usual recommendations. I usually start spraying mine about 2 weeks after planting. Good luck with yours....See MoreWhat can cause my tomato plant leaves to turn brown & yellow?
Comments (15)Do you take mulitvitamin/multimineral supplements such as One A Day or Centrum Nallah? The minerals used in these two and nearly all supplements are chemically created minerals produced by humans and the exact same minerals used in so called non organic fertilizers for plants. Such as potassium chloride, magnesium oxide, dibasic calcium phosphate and many more. We use the same elemental elements as plants do. and extract them only in their pure form known as chemical elements found in the periodic table of elements, if you remember high school science. Chemically created synthetic fertilizers are simply a combination of two or more organic elements, sometimes using high heat, to extract the pure chemical element plants can take in, along with humans. We can't eat phosphate rock or limestone but we can extract the elements of phosphorus and calcium we can consume, same for plants. Soda drink has phosphoric acid in it along with tooth paste, Phosphoric acid comes from treating organic phosphate containing material with sulfuric acid, Sulfuric acid is a natural organic salt of sulfur and also organic. So where is the danger? The idea that man made chemical fertilizers are dangerous is a myth and this is where the danger is. I say a dangerous myth because without man made synthesized fertilizers over half to three quarters of the world population would starve. Not may but would without a doubt. People who think only organic is fine only if they know the facts and not try to force everyone to do the same. it would take 30 tons of cow manure to fertilize 1 acre of crop land to produce half the yield they do now. 30 tons of cow poo requires about 4 cows. 4 cows require 8 acres of good forage land per year. Removing the manure to fertilize your crop land would then reduce the forage available next year. The next year even less, and so on until your 4 cows starve. If you did the same with alfalfa each year the source land would become depleted, and any organic source would quickly become depleted. The world would starve, and organic vs chemica is a major rant of mine because people don't know how sensitive the world food supply is and could easily collapse with the wrong laws by the wrong people. 2,7 billion acres are used to feed the world population and people are starving now, this doesn't include land used for livestock. 2.7 billion acres would require manure from 11 billion cows to support the land by ORGANIC means, but wouldn't last long. You can use organic fertilizers as a personal choice but please be aware most of the worlds population would die without man made synthetic fertilizers made from natural elements that are perfectly safe....See Moreankraras
