I have just purchased a rather large new tomato plant for a pot. Now, I have discovered that the new leaves coming out at the top are a pale yellow. What is wrong? Disease, nutrient problem, transplant problem or what? Help!!
With what? Real soil? Artificial "planting" or "potting" soil or media? Did you add fertilizer? What kind and how much? Did you use a soluble or liquid fertilizer or "plant booster"?
What you're describing is typical of a micronutrient deficiency, but nutrient deficiency symptoms can be caused by many different things, e.g. root damage or disease, overwatering, mineral toxicity, extreme high or low pH, changes in light exposure - all sorts of things that can keep a plant from taking up or utilizing the nutrients it needs.
I have had that happen when I first transplant a plant or they have a growth spurt. They turn yellow at the very center at the top. It has happened so many times I dont think much of it anymore. I think the nutrients just havent had a chance to catch up because the roots are still adjusting. I would watch it for a week or so. Post again sooner if it gets worse or doesnt go away. I have a feeling it will resolve itself. Please let us know if it does get better.
And, now, I want to know the secret to growing bell peppers!! Some one suggested holding back on nitrogen. But, my problem is no peppers to speak of. The plants look fine------in full sun and in soil that grows tomatoes, roses, etc. Many people in my area (central Mississippi) complain of the same problem. There has to be an answer!!
What are you doing up so early or late? Lol. When you say no peppers do you mean the plant blooms and doesn't set fruit or do you just get a few peppers? Can you explain it a little more?
From what you posted great looking plants no fruit I would think the problem is too much Nitrogen also. I grow sweet non bells because I get much better yields of great looking fruit. Marconis are my favorite, but there are many kinds to choose from. Also, I have found that pepper plants can take a little shade.
Thanks for suggestions on pepper plant----------will hold back on the nitrogen--------and will plant in pots that I can move and give plants a little shade.
I am reduced to planting in pots and getting up early due to a weird disease. Ever heard of Giant Cell Arteritis? All the arteries in your skull are infected------------and the worst possible consequence of this is sudden blindness/ and or stroke. The only treatment is immediate and heavy doses of prednisone ( and as many of you know, that brings on its on problems---but is preferable to blindness). The only symptom I had was about one minute of double vision------went to my eye doctor---------he recognized the problem and before I got home that day I had had 2 blood tests and an MRI. The disease can linger for 1 1/2 to 2 years--------as well as decreasing doses of predinosone. The reason I go into this detail is to warn others in case they have any problem with their eyes----go see your eye doctor immediately!!!!!!
