What are my tomatoes doing?

Leaves has started getting tan spots

Did you start them indoors and them move them outside recently?

 

[s0me0nesmind1]

I've tried growing tomatoes in our area multiple times in my life... All times it just ended with tomatoes dying randomly....

I've had damn good luck growing my mangos of all things here =/

could be bugs. release some lady bugs in your garden, and put diatomacis earth around the bottoms. you could spray with mineral oil as well. the oil can help with some fungus and bugs.

looks like tomato plants that went from greenhouse/indoors directly into the outdoors without any acclimation (hardening). If that is the case, they should be good provided the temperatures are not too extreme. Will take some time to recover and possibly longer to fruit.

Dunno ElFenix, wish I knew more about that suff - so many of the nutrient deficiencies (or exesses, burns) seem to look the same. But I will say I do not know why you guys have so much problems with tomatoes - they grow like absolute gangbusters for me, all I do is water daily, mostly twice a day, and I always add like a scoop or two of that Miracle Grow or Expert Gardener soluble general fertilizer to my watering pot, seems to work great!

nope, they've been outdoors the whole time. were small plants a couple months ago when i got them and got pretty huge in a hurry.

tomatoes really don't like our heat much but it hasn't been hot yet.

Has the temperature or the amount of sunshine spiked in your area in the last week or so? I'm following the same logic that dphantom mentioned. It looks like sun scold to me as well.
How often do you fertilize them and what variety of tomato are they? Also if possible could you post a pic of the entire plant not just a close up of the leaves.

 

[ElFenix]

actually the weather was ridiculously nice until today, when it got freaking hot.

the one problem is that there isn't much sun. just a few hours in the morning and then maybe an hour in the evening. one is an early yield tomato that is shade tolerant, the other isn't so it's a bit more of a hope and a prayer.

maybe they just need fertilzed. i dumped some underneath when i transferred them to bigger pots about 6 weeks ago and really haven't since.

i'll get some pics tomorrow.

Miracle-Gro
Works great for potted tomatoes here in cent. FL.
I use a mix of Tomato and Bloom Booster.

Looks like a very minor case of sun scald. The plant should outgrow it.

Pics?!?!

A few considerations.

Is the siding getting hot? That radiant heat and reflected light can scald leaves.

That's a pretty small pot for a large (large plant, not large fruit) indeterminate variety. So it will grown until its roots fail to keep up with demand, then it will get weak.

I see a few small areas of leaf miner damage, but that's nothing to worry about.

Next time you grown an indeterminate variety in a pot, tip it after it sets its first two flower sets. Or plant a patio (type) tomato.
Tipping and training a tomato plant, removing leaf axial branches...all things to consider when you want healthy plants and to maximize ripe tomato production in pots and planters.

Gardening is one of areas of expertise where it is essential to have some resource material at hand. You can still find this book used, its great.

Yes the pot is too small. Before I saw these latter pics, the damage looked more like bacterial or fungal leaf spot to me. I still wonder if you have that from rain bouncing off the siding.

Insufficient outdoor hardening tends to either more uniformly affect the entire leaf, or create a dead light border around the perimeter of the leaf, but tomatoes are far hardier against this than other plants unless there is an extreme sunlight difference.

On that note, yes you need far more sun for good production but then an even larger pot. A 10 gallon pot would be a good start. This will also make watering and fertilizing much easier. I don't even grow tomatoes in pots unless I have surplus sprouts and pots, otherwise all major production plants go straight in the ground.

Time to put them in the garden not a pot.

That does look a bit like a fungal infection. Early girl is not a bad cultivar. Better boy is good, too. I once grew a single plant of Super beef-stake. That thing grew like crazy and made monstrously big tomatoes.

 

[Scarpozzi]

How are the plants doing? I just saw this post and first thing that comes to mind when I see off-color in leaves is that it may be fungus and I see Iron Woode said the same thing. I recommend getting a sprayer and spraying your leaves with milk. Look it up...it helps curb that stuff without introducing something too nasty.

Also, sevin dust is good to keep the bugs off.
