Designed to boost Phosphorus (P), Potassium (K) and Trace elements levels during the flowering and fruiting stage. After renewing the working solution, during the first few days, plants absorb P, K and Trace elements at a rapid rate. As levels fall, the growth rate begins to slow down. Using PK Top Up regularly gives your plants a continued supply of valuable Phosphorus, Potassium and Trace elements when it's needed most.
WHEN TO USE:
Using PK Top Up once flowers begin to form. PK Top Up is suitable for all "run to waste" and "re-circulating" systems. Regularly flush your system to prevent nutrient and plant wast build up.
