Hi
@dancingshrubbery! I think the yellow spots are not related to bugs/pests. The dark & almost glossy foliage makes me think of a slight Nitrogen abuse for the last weeks, and as as result, the rootzone is having hard times trying to handle Phosphorous intakes. You must stop BioGrow as soon as the stretch has ended (~week2 of flowering stage), this explains why you're having some deficiencies. Flush your medium with plain pH'd water, and stick to BioBloom + TopMax in your next feedings. LaughingBuddha is one of the best weed I ever smoked in Amsterdam, you will have fun 😎 Hope this will help, keep us up-to-date and happy growing 👊
