Had some brown algae this week, learned the importance sealing off ALL light to the roots, cooling res temps with ice bottles 😎 and I reduced the nutrient mix a bit by taking away the supplemental like “Fire” and “Prime”. I will be resuming them next reservoir change which is tomorrow since we have solved the brown algae issue and have seen full recovery, Unless I caught it fast enough to avoid any slow down, which I believe I may have!
