Mine are fine, but that doesn't mean do it to every plant you have straight away. Everyone's situation is different and I have been battling gnats that came in my soil for the entire grow. Also my ambient CO2 is around 700-800 depending on which plants are sleeping so nutrient uptake is accelerated. I chose to top dress with Neem Cake and water instead of drench with Azamax early on when the seedlings were more fragile. Heck I even brush my teeth with Neem and Tea tree toothpaste......But the Azamax bottle says keep away from children and contact poison control............ So I use Einstein oil for foliar application as it is less refined and I am more comfortable spraying it.
