Backyard Aquaponics
A place to discuss aquaponics

In same GB as other which look fine. All others look fine. Looks like a nutritional deficiency, but seems weird being in the same bed with other...which all look fine. Help.

I havnt got my binoculars but first glance looks like its suffering for water...?

new growth is distorted, lots of yellowing new growth, midrib is kind of inverted with edges of leaves turned up. Eventually, leaves turn all green, but leaf edges still curled up and midrib is still distorted. have some blooms...see what happens to fruit. Looks like it could be Phosphate or Magnesium issue...but tomato 1 foot away looks fine???
weird.

Curling tomato leaves may be a sign of a viral infection. Normally this virus is transmitted through whiteflies or through infected transplants. Flowers may still develop but they will usually drop off and fruit production will probably be reduced.

Too much or too little water also causes this reaction.

First, check to see that you are getting enough water to the root zone of the affected plant. Adjust as necessary and watch for results. If too much water is getting to the rootzone and the roots are always submerged then you should adjust your flow to the bed so you have a couple inches (2" is the norm I believe for a 12" deep bed) below the top of the media. Not enough water, then adjust to raise the level as suggested above or you could try replanting the tomato plant deeper.

Second, if water is not the issue then it is best to remove the affected plant. The reason I say this is because you have another plant nearby that is not affected. Best to prevent the same problem on the other plant.

you could also just leave it and see if it recovers. Look closely at the leaves, leaf nodes (where it attaches to the stem) as well as along the stem for whiteflies.

This is just how I would approach it. Check the water level first and adjust. Leave a couple days and re-evaluate.

I had 1 tomato plant out of 4 that stayed very small for about a month and a half when the other 3 had grown 2 feet. It just woke up and took off one day. I kept it in but then later on it started not doing well so I pulled it.

Thanks for the tips. No insects,I inspect daily with hand lens. Don't think it's water, as all other plants in GB are fine and depth is at appx 2". Could be virus, but doesn't match any that I've seen. Looks more like nutritional to me, but still baffles with why other tomato looks fine. See how blooms develop and if they don't set fruit, I'll remove as my heirlooms are now coming up in the seedling trays and will be ready in a few weeks.

Hi Chris i have plants that are only a foot apart and have different nutriional deficiencies. imo this is due to the plants being able to extract or not, minerals from the solids in the bed. again in my view the water is not the only source of nutrients. i would not discount nutrient deficiency (or virus)

Looks viral to me. I would pull it and bin it before insects spread it to other plants.
