Tobacco Mosaic Virus or Environmental Stress.

[Parcgreene]

I've got a major problem with my ebb and flow hydroponic tomatoes. The branches are curling/coiling up and the leaves are leathery and brittle and also curling upwards. The new growth doesn't have this problem, it starts with the older leaves and works upward. My plants did the same thing last year, I'm wondering if the Tobacco Mosaic Virus was the culprit last year and now this year it has been re-infected. I don't know much about the TMV, and what I've read online hasn't convinced me whether or not this is the problem.

The fruit seems to be developing normally. I thought perhaps the issue was an environmental issue, here's a list of things I've altered checked:

Started using reverse osmosis water instead of tap water.

Changed nutrients from GH Floramato to Hydro-Gardens commercial tomato formula.



Altered flood/drain schedule various different ways.
None of these changes had any effect.

I have a garden hose with a metal end attached to a pump that is attached to my aquarium chiller. Could the low ph of the water be degrading the metal and producing some sort of metal toxicity?

Also I have a family of tree frogs living in my reservoir so there is a small amount of frog excrement in my reservoir.

All of my plants are different types of heirloom tomatoes.

Thanks for your time to read this and hopefully help me with a diagnosis and solution.
