PK TOP UP is formulated using high quality soluble ingredients and designed to supply additional levels of phosphorus, potassium
and trace elements levels during the flowering and fruiting stage. Potassium and phosphorous help improve flower and fruit colour as well as enhance the flavour of the final product. PK TOP UP’s highly concentrated formula means you only need a small dose to achieve fantastic results.

During early flowering and fruit set, plants absorb higher levels of phosphorous and potassium. As levels fall, the growth and flowering rates can slow, leading to aborted flowers and fruit. When used regularly, PK TOP UP can be used to quickly correct deficiencies or simply to return phosphorus, potassium and trace elements back to optimal levels.

Continue using NITRO-K until there are visible signs of flowers and buds then start using PK TOP UP. This will ensure a continued supply of potassium for flowering while nitrogen is replaced by additional phosphorous needed for fruit production. Using the two products in succession will give improved colour, flavours and yields. The results will clearly be visible in the quality and yields of the final harvest.

Tired of low poor quality yields – Now it’s easier, Top up your yields and give yourself a better quality harvest!
