No, the tomatoes are in aeroponics, I should have specified sorry. They did get a little dried out a couple days ago, but looked to be rebounding and this happened.

The reservoir was 3.6ec and 7.2ph, so I adjusted it, but I don’t know exactly what tomatoes like for a range yet. The others seem happy, so hence the confusion.

Oh I don’t know anything about aeroponics, sorry. But it does look like it could be heat damage or something, hopefully with the lights turned down it will recover. Different varieties will have slightly different environmental tolerances, and temperature could vary slightly depending on their position, so that could explain why only some were affected.

Good news is that it doesn’t look like any disease or nutrient issue I can think of.

The light has a really intense Cree cob on each side, one being 2600k and the other being 5or6000k, can’t recall. So maybe it just doesn’t like the one wavelength over the other. One’s better for flowering plants and the other is better for vegetating plants.

The one plant that looks perfectly fine is actually under the one that burnt out last week, which tipped me off to maybe light intensity.

This can't be the same group of tomatoes you posted about a week or so asking whether or not you should cull, right? These look like pretty beefy plants, learning curve aside. I hope you can adopt your methods and the plants recover!

8 days ago I culled it down to 4. This aeroponics system is honestly boggling my mind with how good it is, and how untuned it could be. Maybe I got it dialed in accidentally first try, totally possible.

I think it’s just about time to drop it to 2 anyways, I’ll need 4 ports for my cannabis starts here shortly.

That's nuts. I have a bunch of tomato seedlings in dirt under lamps and they're growing a ton slower than that. Congrats!

I’m gonna try and make a comparison using the soil ones vs my aero to see the difference when they get further.

That tomato looks kinda thirsty to me. The leaves tend to curl inwards in an attempt to preserve moisture. Also tomatoes generally need slightly acidic soil depending on the type. Good luck and keep us updated!

Appreciate the insight, it’s in Aeroponics and the roots don’t look rotted, but I did notice the plug is very moist near the stem, could that be an issue?

I’m thinking it’s transpiration related, but many factors there. I am leaning more toward light intensity as some of the curled leaves are nice and crunchy, so they got toasted regardless of other issues.

Will do, I’ve got my garden starts in soil, so it will be interesting to see the progressing comparisons.

With the way the leaves are shriveling I think it's too much heat or light. They're not turning the colors I'd expect if it were low water.

Maybe give it a "cloudy day" to recover with minimal light/heat

Is this a kratky setup?
