Just guessing, but perhaps there are few a lessons to learn -

- Make certain the plants are thoroughly moist before spraying with anything.

- Temperatures matter - how hot or cold was it?

- Dosage matters -- Did you follow label directions as to how much per gallon?

- Plants grown indoors are very sensitive to sprays of any kind.

indoors or outside??? ... did you remove them from sun after spraying??? ...

what product.. a true soap ... or homebrew??

Hi! These were outdoors and it was a cloudy day. Temp was about 70 degrees. In Houston we plant tomatoes at the end of February. I used safer Brand insecticidal soap and diluted it as label said. The plants are still droopy but leaves are all still green.
