61% phosphate, for the moments a base feed alone can't cover
RAW Phosphorus gives plants the phosphorus they need in a water-soluble form, containing 61% phosphate (P) and 9% ammonium nitrogen (N). Phosphorus is used mostly during early rooting but also provides the energy that drives fruit and flower production later in the cycle, so having a straight, high-concentration source available means a deficiency can be corrected without disturbing the rest of the feed.
It is safe to use throughout the grow, including as a foliar feed, and safe alongside other nutrients — making it as useful for building a fully custom feed as it is for a one-off correction.
