Hydroponic tomatoes

Didn’t see a forum for hydroponic gardening so posting here. I have some small white bugs and green bugs on my tomato and pepper plants and looking for a DIY spray to get rid of them. Anyone with a recipe that works without killing the plants?

We have the https://permies.com/f/106/aquaponics forum where most folks post about hydroponics.

Your questions seem to fall more under bugs or predators though.

I have found that my used dishwater works for killing a lot of bugs.

Here is a thread that might offer some solutions:

Do you have a picture of the bugs? Maybe they are aphids. Aphids and other sap suckers or leaf munchers are attracted to plants that have excess nitrate and sugar building up. It could be due to hidden hunger from low level of certain elements even before any visual symptons. . For example, sulfer is a secondary micronutrient that is often overlooked. Plant needs similar amount of S as P and it works synergistically with nitrogen. If you use the all purpose plant food, look up the ingredient chart sometimes the S number is not shown. In one common brand, I calculate it to be 24-8-16-4 for NPKS from the amount of ammoniacal nitrogen and metal sulfates. If there is sulfur deficiency, an epson salt foliar spray will help. Though I am not doing aquaponics, I used to have pest issues with overwintering indoor pepper and tomato. This year I paid special attention to nutrition balancing and all my plants are now free of pest.

Thanks guys. Here are a few oics

John Kempf talked about how nutrient deficiency can make plants susceptible to aphids.

Maybe you can go through the checklist and see if any number is out of range.

I also see there are a couple parasitoid wasps in the first picture, they will do the natural pest control for you. Maybe I already found some aphids turning pale and bloated.

Some hydroponic growers recommend potassium silicate as foliar spray to strengthen the cell wall for better disease and pest resistance.

I merged your stuff with the following thread. I hope that is okay by you.

Anyone on here growing hydroponic tomatoes? Iam do a Dutch bucket system and having some issues with my plants, leaves curling. Ph at between 5.8-6 mostly and ec around 2.

I am not sure if it's relevant but I see similar thing happening tomato leaves indoors without adequate air circulation.  The leaves are curling outwards trying to increase surface area for more transpiration, the opposite of rolling inwards under water stress.
