No... neem oil is an organic foliar spray used for pest control. I wouldn’t use it at all unless you’re having some pest issue.

Unless you are having pest issues you don’t need it. If you are then follow the directions closely on how much to add to your water.

My first grow and I suck so I overwatered, too high temp, wrong PH for a couple weeks resulting in stunted and tiny plants. I'm just getting the hang of it this last few weeks.
Will my stunted plants still able to produce potent buds even of small quantities?
Thanks! 😄Week 6

Some leaves are showing small burnt spots and slight curling. what could be? I'm currently dealing with Fungus Gnats in the grow. I applied Beauveria and covered the soil with burnt rice husk. I’ll wait for the soil to dry and then use hydrogen peroxide to try eliminate the eggs.Leaves. Tips - Burnt

Root aphids in flowering?What I initially thought was a nutrient issue I am now convinced is a root aphid issue. Noticed a few small white bugs crawling on top of the soil and I don’t know how to get rid of them without harming my plant. She’s in 5th week of flowering so I don’t think neem is ideal.Other. Bugs
