Strengthens plant structure during heavy fruiting stages. With most nutrient brands, ‘Flowering Enhancer’ avoids needing a ‘calmag’. Unlike regular PK additives, Flowering Enhancer helps lock pH below 6.5 by improving the nutrient’s pH buffering by over 500%.  This prevents pH related deficiency symptoms, even when hard water or alkaline additives are used.
