Peters Excel 'CalMag':

Calmag Finisher

13+5+20

• Often used as a follow-up to the 15+5+15 CalMag Grower.
• The high potassium formula leads to more compact growth.
• The same principle applies to this Peters Excel product too: a 'single-tank mix' solution providing the plants with all the necessary nutrients from a single tank.
