Nutrient Deficiency?
I think my tomato plant has some sort of nutrient deficiency..but I'm not sure which one. I have a Bonny Best tomato plant in a container, fertilized with 6-18-6 spikes (although it doesn't mention micronutrients, so it may be entirely lacking in anything except the big three). I water pretty much daily since it's very hot here.
Bascally, the older leaves on the plant seem to be just fine while all the young leaves are yellow/yellowing. Most of the yellowing is interveinal chlorosis, although a lot of the leaves also have tip burn around the edges. From what I've read, the nutrient deficiency is in one of the "immobile" nutrients since only the young leaves appear to be infected. Many of the leaves are also curling.
I think it may be one of these:
Iron
Zinc
Calcium
I may also be overwatering, which I've read can make it hard for both iron and calcium to be taken up. I'll lay off the watering and see if that helps too.
Here are some pictures of what the problem looks like. I was having a hard time taking pictures of accurate coloring, it comes out either too yellow or too dark. But it gives a decent idea:
Comparison of young leaves to the older leaves.
Some young leaves with interveinal chlorosis
More young vs. old:
Any ideas?

How to tell mineral or nutrient deficiency in plants and soil
Comments (160)Jue Shei: for the 1st picture, you are right that the whole plant is not pale, but only the upper leaves. I look at your 1st pic. three times, and it looks like iron deficiency (dark veins on pale leaves). See below excerpt: "Iron Deficiency: Caused by High soil pH and salinity. - High Phosphorus, Manganese, Calcium, Molybdenum or Zinc levels. - Soil low in organic matter & Insufficient drainage. Leaves become yellow or near white between their veins. Stunted growth." From Straw: For your 1st pic., it looks like high soil pH (wood ash has pH of 13), plus salinity or high salt (wood ash is very high salt). If you did NOT put wood ash in the pot, it can also be poor drainage. My rose in soaking wet clay has that problem during heavy rain. If water cannot drain fast from a pot, upper leaves can have iron deficiency (pale background with darker veins). If it's a high pH problem from topping with wood ash, then scrape off the topsoil When the soil inside the pot IS NOT changed every 2 years, then the soil becomes compact and water can't drain fast, roses will turn pale. My most dark-green roses are with NEW potting soii which is fluffy and has air for root growth. If your soil is more than 2-year-old in the pot, then change to NEW SOIL will help. Old soil in the pot for more than 2 years accumulate too much salt, then become compact so roots have zero air, so leaves turn pale. From the web: "An ideal soil contains 25 percent air, 25 percent water, 45 percent minerals and 5 percent organic matter."...See MoreIs this a nutrient deficiency?
Comments (6)Some soils when they get overloaded with water that can cause the nutrients not to get to the rose leaves making it appear to have a nutrient deficiency. So you sort of got to figure out if that's it or not....I've had rose leaves look like yours when I had to much mulch under our roses and lots of rain, I pushed mulch back away from under roses and soil dried up and the new leaves got better... If you start seeing multiple rose bushes with bad leaves throughout different sections of your garden let your soil dry out and see what happens......See MoreGardenia nutrient deficiency?
Comments (1)Since gardenias are acid lovers, iron chlorosis is my first thought. Iron tends to be bound in not sufficiently acidic soils and its lack of availability will lead to the yellowing or loss of color between veins. Lack of other nutrients and other cultural conditions can produce similar symptoms but with acid lovers like gardenias, an iron deficiency is typically the cause....See MoreThrips? Cold damage? Nutrient deficiency? Help with snake plants!
Comments (15)Agreed with above comments. Once damaged the Snake plant doesn't show it soon, leaving many to believe it is okay. Then a month later, you see what yours looks like. Damage will never repair itself but will out grow it with new leaves and pups (new young plants). There are many factors that can cause a plant's demise. Mostly keep warm, out of drafts and all the bright light they can get. With warm weather (80's to 90's) they require all the water possible. I have seen some sitting in water all the time! Most people don't keep their house that warm and hope you can take them outside for summer vacation. A large well grown Snake Plant can take a lot of abuse being in darkness and little water and even temps in the 50's, but if something does go wrong then it will advance rapidly....See More
