Potash, Phosphorus and Trace elements

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.
