Description
Epic Blast is a late-stage potassium and phosphorus booster intended for use during the final two to three weeks of flowering. The elevated K level at this point supports the movement of sugars from leaves into developing flowers and promotes the dense, compact structure that distinguishes properly finished fruit and flower from underfed equivalents.
The typical approach is to use Epic Blast as a partial replacement for your base nutrient during the ripening period rather than stacking it on top of a full-strength feed — this keeps overall EC in range while shifting the nutrient ratio toward what plants need at this stage. Run at your target EC with the base nutrient reduced accordingly, continuing until you flush or move to a clearance product. Compatibility with most base nutrient lines makes it straightforward to introduce into an existing programme.
Late-stage boosters like Epic Blast work by shifting emphasis rather than adding volume to an existing feed, which is why the recommended approach is to partially replace base nutrient rather than simply adding the booster on top of a full-strength feed — stacking rather than substituting tends to push EC beyond the target range and risks nutrient burn rather than the intended finishing effect. The 5-litre size suits growers running the product across a full season or multiple rooms, where a smaller bottle would need reordering mid-cycle. As with any concentrated additive, dose accurately using a proper syringe or measuring device rather than estimating by eye, and introduce gradually if you haven’t used the product before, watching plant response over the first few days before committing to the full recommended dose for the remainder of the ripening period.
Store the bottle upright in a cool, dark location between uses to preserve potency through to the end of the season, and keep a dedicated measuring syringe for this product alone to avoid cross-contamination with other concentrates in your feeding programme.
