<span class="link_user">@Fridolin420</span>, If you are new, best advice someone gave me was to ensure pH accuracy. 5.8 always works no matter which media you are in. When you get to last 2 weeks and leading into flush, hit them with 6.0 to 6.1 pH if you want pinks and purples to be more vivid. Best of luck!! Your plant looks flawless perfect so far
