This is where to look for Cookies phenotypes in the Pink Platinum crosses. Roughly half the population displays vibrant pink or dark purple coloring. Flowers grow dense and resinous with extreme potency. Some anxiety has been reported from testers so this is a cross for experienced smokers. We recommend tapering nutrients at the end of flower (if not growing organically), instead of cutting to plain water at the end, to reduce the plant’s stress response and encourage terpene production. Also, some phenotypes are very sensitive to light. As such, along with maintaining a fully blacked-out dark cycle with no light leaks, we recommend growers either “lollipop” the plants (strip all lower nodes that do not receive intense direct light) or monitor the plants diligently during weeks 3 and 5 of flower, removing any male parts. In summary, the plants that are easy to grow are very easy to grow, but you might have to “weed out” 25% of them in a test run before flowering a full room of them without worrying about unintended pollen… but you’d do that anyway, of course, right? 😉
