Hi Soggy,

I do not suspect TMV but rather a nutrient deficiency or uptake problem.

The problem with deficiency diagnosis is that there may be multiple (even light) deficiencies that interact with each other. One has to compare symptoms on younger and older leaves, if there is intervenal chlorosis or only venal clorosis or a combination. Very detailed pictures (showing these aspects) are needed to be interpreted by the book, and to do a matching diagnosis.

Is it FLORAMATO DRY™ what you are using? Unfortunately they do not give any specification of this product, and I am used to analyse nutrient formulas with their actual PPM content in macro- and micro nutrient. That's how you can guess what may be lacking (in case).

Mostly, dry mixes lack calcium, because calcium nitrate is not compatible in dry- or liquid mono-mixes. If you have soft tap water with enough calcium this might not be a major problem. If on the other hand, you unluckily have got hard and nearly calcium-free water, a dry nutrient without Ca is not appropriate for Tomatoes. Enough Magnesium and Sulfur should also be part of any decent tomato formula.

You can simply (in combination with the spray) get rid of them by brushing them off with a soft 1 Inch painting brush, holding a paper sheet with the other hand to collect them. Get rid of them as they weaken your plants gradually and may be carrier of other pathogens as well!

Check the Ca content of your product, the Mg as well and even Iron content. The light colored leave-veins could also point to a lack of potassium. Some necrotic (black or dark brown) spots or leaves or stems may also come from a K (uptake) problem.

What about PH and nutrient temperatures, - and what about climate and actual air temperatures, sun exposure (partial scorch)?
