<span class="link_user">@StalCair</span>, If you want to go with the neem oil it will kill them immediately. It's strong stuff so follow the directions. Your just starting to flower so you can squeeze in a treatment or 2 if needed. Leaf miners won't really be effected since they are inside the leaf but it will kill the flying adults that lay the eggs.
<span class="link_user">@Philindicus</span>, hey dude. There are quite a bit of insect traces here and there. Just spotted another thrip, might be some mites too and even saw one leaf miner inside of one of the lower leaf. I removed the leaf infected and ordered black soap and neem oil to apply to the plants. I hope it will work if it is not too late. Preflowering is almost over and applying neem oil leaves a bad taste.
Should i just use potash soap?
