<span class="link_user">@Cannabeast40</span>, Thanks, G! My mineral-fertilized plants were almost perfect, but now I'm learning a new growing method and I can see that I've ruined my nutrient soil mixture. There is a lack of oxygen in the root zone, which creates an unstable environment for nutrient uptake from the soil. But once I get everything up to peak performance, as with mineral fertilizers, I believe you'll have something to look forward to.
