best leaf insects repellent
I have found a few bad insects on my plants past weeks. Does anyone have experience with neem oil? Is it worth a try or would I be better of buying something else? White vinegar with dishsoap didn't help much. The bugs are: grasshoppers, stinkbugs, spidermites & fungus gnats.

Plants deteriorating rapidly, pls help
Plants not looking good! Help! White tips at the end. Brown patches. Leaves curling. I've been feeding it 0.5L Advanced Nutrients Coco Big Buds. The light was fairly close, at 30cm. I've raised the lights to 60cm. It was also very humid, so I've opened the air vents .
