There are multiple things that could be In play, but the fertilizer schedule seems pretty intense, especially since the planting mix already contained a fertilizer. What are you using and at what strength? Why so frequently? Any pesticide use nearby?

Thanks for answering. No pesticide use. I mixed the dry Trifecta+ fertilizer into the soil in late May. That’s the only time I’ve used that fertilizer. I do add a fish emulsion fertilizer to this plant once every two weeks.

I water without fertilizer every morning because the soil feels dry one inch down at the end of each day. Perhaps too much sun?.

Oh and I diluted the Fish emulsion fertilizer to the recommended strength of 1tbs per half gallon.

im not clear whether you fertilize twice a week as per your first post or every 2weeks as per your response. If the second then maybe that is not the problem. I usually use a wooden skewer plunged all the way down to see how wet the soil is midway in the pot. Is it possible that the pot is waterlogged? My tomatoes love sun and just look wilted if they begin to dry out. Let’s see if some others will chime in. it will help others to know where you are

I edited the original post for clarity. I fertilize once every two weeks.

The potting mix in your photo looks very dry... the easiest way to tell if it needs water is to become familiar with the weight of the pot when it's fully watered vs when it's completely dry. Once you know the weight, you simply have to tip the pot to feel if it's lightweight and therefore needs water.

The pot is way too small.

Pot is too small. Plant possible need calcium or potassium, or both. Get a device which will measures a moisture in the pot, it will tell you how moisture soil is, so you are not under or over watering it.

has that thing even produced a blossom yet?

No it hasn’t.

I have another tomato plant growing In an identical pot (10 feet away from this one but with same levels of sunlight and on the same watering schedule). The other tomato Plant looks great, has blossoms and 4 small tomatoes growing.

I’m starting to think that this one might simply have a disease

I really believe the plant has and excessive amount of nitrogen, and why I asked about any blossoms. The big curled leaves and thick leaf stems are a sign also.

ahhh I hadn’t thought of that. Thank you. Do you think it would be best to cut Back on fertilizer?

This is so very helpful! Thank you!

Kevin9408, what if one were to grind up banana peel in the blender and mix with water. Would that speed the potassium uptake?

Yes, it would speed up decomposition and the microorganisms will release the potassium as available potassium for the plant.

At one time I dried out banana peels, weighed them for an average weight, calculated the potassium mineral in a gram (this data wasn't easy to find) along with the potassium requirement for an average tomato plant over an average growing season and came up with 3 to 4 peels. One peel won't do it, and they should be spread out over time.

@outpaientzero thank you so much for your advice. My tomato plant sprouted it’s first fruits earlier this week 🙌🏾

Glad I could help and hope you get a bunch of tomatoes.
