The balanced grade used through most of the vegetative stage. Fully water soluble with negligible residue, so it passes through drip emitters without clogging them.

A high-phosphorus starter grade for the first few weeks after transplanting, when the crop is putting down roots rather than making leaf.

A nitrogen-free grade for the flowering and fruit-set window, where extra nitrogen would push the plant back into leaf.

Feeds potassium during fruit filling and sizing, with just enough nitrate nitrogen to keep the canopy working.

Corrects the calcium deficiency behind blossom end rot in tomato and capsicum, and tip burn in leafy crops. Do not tank-mix with sulphate or phosphate grades.

Epsom salt for the interveinal yellowing on older leaves that signals magnesium shortage, common on sandy soils and in long pot culture.

A chloride-free potassium source for crops that resent chloride, and where fruit quality and shelf life matter more than bulk yield.

An acidic grade that helps keep drip lines clear while supplying phosphorus, useful on hard water where scaling blocks emitters.
