Tomato Nutrient Deficiency

This appears to be a symptom of nutrient deficiency. These deficiencies could also be symptoms of too much water, or watering too frequently – we noticed its in a pot, so make sure water is draining from the pot every time you water, but only water when the upper 2″ (or a bit more depending on plant size and root ball size) have dried out. Soil that are too wet cause roots to drown and not function. Sometimes not enough water can also cause root damage that results in insufficient uptake of water and nutrients. Tomatoes are heavy nutrient feeders at certain stages of growth, and nutrients can be difficult to provide if the plant is not growing in ideal conditions. Here is a link (from the University of CA) all about Tomatoes that will help, but in short Tomatoes need 6-8 hours of full sun each day, and prefer not to be watered “overhead”. Since your plant is in a pot, you may eventually need to water more often as it continues to develop a bigger root system, but don’t “over-water”. If your plant is well on its way with flowering and fruit set/development you should fertilize it with an all purpose vegetable fertilizer or something formulated for tomatoes – consider a slow release fertilizer so that the plant gets a continuous feed for this period of heavy use. Follow the label instructions when fertilizing. http://www.ipm.ucdavis.edu/PMG/GARDEN/VEGES/tomato.html
