Disease or Nutrient Deficiencies?
Comments (4)not sure did you do a search for tomato and cucumber diseases and bugs?? for me if the plants are producing well i'd leave them be. just at watering time i'd be suggesting only water around the root zone not over the foliage. how much sun do they get? they will need around 6 hours per day in the morning is best. do you mulch them at all? you should do, use a spoilt hay type mulch. len Here is a link that might be useful: lens garden page...See MorePlant Nutrient Deficiencies.

Comments (8)Mike, good idea to post symptoms here, but since it is a citrus forum, I should point out that in many cases, the symptoms you've listed don't occur on citrus, and that the actual symptoms on citrus are quite different from those listed. For example: Calcium -- seldom visible symptoms on citrus Magnesium -- never symptoms on new growth of citrus; old growth shows a characteristic "inverted V" of green at the base of the leaf and yellow-orange above. Phosphorus -- I've never seen a citrus tree exhibit the purpling of leaves; rather, reduced fruit size and yield is most common. Boron -- in citrus, shows up as dead, sunken, gray or brown areas in the albedo (white part) of the fruit peel. Usually no other symptoms. Copper -- Growth may be unusually vigorous, producing huge, deep blue-green leaves, but the stems are too weak to support the weight, so they bow unusually, giving what is known as an "S" shape to the limb. Also, such limbs develop blisters on the epidermis which swell, then burst open, and ooze a sticky sap. Then in areas of the world that have fire ants (e.g., Florida), the ants are attracted to the sap, and they chew away the epidermis, killing the twigs entirely. Manganese -- at least in Florida, even a fairly severe deficiency generally has no effect on yield. Molybdenum -- older leaves are green with large (up to 1/4") yellow spots, like large freckles....See MoreKumquat dropping leaves, some disease?
Comments (5)Yikes! That's REALLY high in N, even for citrus,Very strong fertilizer, I think rather overpowering for a container plant, personally. And yes, I would say this may be nitrogen burn. I would re-pot, flush the roots and switch to DynaGro Foliage Pro. Be sure you've got a well-draining potting mix. Some of this may also be due to wet roots. Most container folks use 1/2 strength Foliage Pro with each watering, full strength during the later spring and summer, when citrus are outside and really growing.

Comments (2)I have a very similar problem to Jean001a's problem. I think I have an infestation of spider mites causing this problem. I did see some very tiny bugs as well as some small webs. The leaves of my tomatoe plants turn dull and turn almost white. THe fruit as it ripens gets a blotchy yellow coloring. I have the same problem on some eggplant plants (leaves turn dull and white, fruit sick). Someone told me to spray the plants with a garden hose to get rid of the spider mites. That does not seem to work. Do you think it is spider mites? Is so, what is the best,safest way to get rid of the problem. I have pictures I can post but I cannot figure out how to do it on this response to an existing message....See More- 7 years ago
