Stonerdanswered grow question 4 years ago If you want a more organic and DIY insecticide that helps against Thrips try using neem oil (dosage according to instructions) in tomato leaf water/extract in water. The tomato has a strong natural resistance to pests and will help a lot against them!
You can also add yellow/blue sticky traps to get rid of them faster!
Btw I'd suggest lowering the Nitrogen (N) dosage by about 20-30% since your plant is developing signs of toxicity - Dark green foliage with tip chlorosis (burn) from bottom to the top of the plant
Hope this help! Good luck and happy growing :)
