Elium

Optic Foliar Elium (formerly ATAK) is a dual-action foliar spray that both treats powdery mildew (PM) on cannabis leaves and boosts overall plant health. The dual action immediately combats and eradicates existing PM on leaf surfaces while simultaneously providing a plant health boost — trace minerals, biostimulants, and immune-supporting compounds that strengthen the plant's ongoing resistance to future infections.

Powdery mildew is one of the most common and damaging fungal pathogens in cannabis cultivation, and Elium provides a front-line organic response that doesn't require harsh chemical fungicides. The plant health boost component means Elium contributes value even when PM is absent — using it preventively maintains plant health while guarding against future infection.

Apply to all leaf surfaces at the first sign of PM or preventively during high-humidity periods. Uses Optic Foliar's lights-on safe technology for daytime application convenience. Made by Optic Foliar, Canada.
