..... hard to say precisely what's wrong w/o more info, but they definitely don't like dishsoap on their foliage or in the root zone. Something I wrote:

Detergents

Dishsoap/ detergent’s effect on plants varies with the mode of exposure. Dawn, Palmolive, Joy, ...... dishsoap, as an example, are each and all a mishmash of chemicals, at least eleven of which are phytotoxic. If the top of the plant is sprayed thoroughly with even mild detergent solutions such that all surfaces including leaves are covered, the detergent can easily dissolve the protective coating of cuticular wax on the leaves of the plant, causing abnormally high rates of water loss and possible necrosis of all or part of the leaf. Cuticular waxes prevent leaves from drying out, and help stop pathogens from attacking the leaf. Strong solutions will even dissolve cell membranes, causing death of the cells.

If a detergent solution is used as a soil drench or makes its way into the soil as a consequence of over-spray or run-off, the effect on roots is immediate. Because one of the main function of roots is to absorb water and nutrients dissolved in water, they lack the waxy protective coating that leaves employ. Detergent solution in contact with root cells can quickly dissolve the lipid membrane surrounding cells, killing the cells and inhibiting water/ nutrient uptake. Hair cells growing as appendages off larger roots do the lion’s share of assimilating water and nutrients, and these very delicate cells would be the first casualty of any detergent in the root zone.

There are widely available insecticidal soaps, designed to be used topically and made mixing potassium with only long chain fatty acids, carefully selected and specifically formulated to be safe for mammals & birds, death on most insects they contact, and most important, safe for plants. If you need something "soapy", it would be much better if you selected a product intended for use on plants than one intended for other purposes.

Also, neem products are not all created as equals in effectiveness or how plants react to them. Best is a pure, cold-pressed neem product such as that made by Dyna-Gro.

This might help you. (click link)

The soil looks very dry in those pots where we can see it. Also, why is the window blind closed?

Why are you hitting them with dish soap and neem oil if you don't really have a problem?! I'm assuming you're in the northern hemisphere -- it may be a southern window, but the blinds are set to block light and the plant shelves look like they're in a darkened corner of the room, well back from the window. I also think the soil looks very dry in all your photos. I'd water them well, stop spraying them with things, and give them some decent light.

@tapla thank you! When I first got neem oil I was told that's how you mix it so thank you for clarifying.

@floral_uk z.8/9 SW UK @party_music50 I think the grow lights distorted the lighting here, it's not typically this dark even though it rained today. This corner gets the most sun in my apartment by the way the sun moves. I could put the plants on the second plant stand next to the windowsill, but I thought the light would burn them. I thought I was supposed to provide these plants with filtered light, so I kept the blinds down but open. I previously had a bug problem and when these plants started acting up, it looked similar so I sprayed them. I use a moisture meter for watering and they all are still moist, not wet or dry, and if over watering was the issue I didn't want to drown them with a drink.

Id say those grow lights aren’t providing much if anything at all.

keep the window open, move the plants in front of the window.

if you want to use grow lights, that’s great, but you will need some with a lot more power.

more of the lights you’ll find on amazon are junk.

Potting soil is even so visibly dry with the one bigger leaved plant in the one shot it looks like it has shrunken away from the walls of the pot.

@Embothrium I'm not sure which one you're referring to, but all my plants are either wet or moist either on top or an inch into the soil. I worry about overwatering and use my finger or moisture meter to check. I'm trying my best...

Have you fertilized the plants in the recent past?

@iochroma yes, I have semi-recently. I've also over-fertilized before trying to be careful.
