Hy-Gen PK Top Up
PK TOP UP is a formulation designed to replenish Phosphorus (P), Potassium (K) and Trace elements levels in your nutrient solution through all stages especially during heavy ﬂowering and fruiting. Trials have shown that during the ﬁrst few days after renewing the working solution, plants absorb P, K and Trace elements at a rapid rate. This is usually visible by an initial burst in growth rate and ripening of fruit. After a few days the growth rate begins to slowdown.
