Field Marshall Critical Mass 5 Litre
Critical Mass is an advanced PK additive for mid to late flowering. It can be used by growers using hydro, coco or soil.
Phosphorous (P) is a macro nutritional element for every plant. It is a vital component in the process of plants converting light energy into food, fiber and oil.
It plays a key role in photosynthesis, the metabolism of sugars, energy storage and transfer, cell division, cell enlargement, and transfer of genetic information.
Potassium (K) is essential in the manufacture and transport of sugars and starches and in cell division.
Potassium ensures the plant produces enough sugars during flowering, which are essential for the development of the fruit and flowers.
Potassium also increases a plant’s resistance to diseases and mould which become more prevalent with increasing floral size and density.
As flowering plants progress through the reproductive stage their potassium requirements increase in relation to their phosphorus needs.
Critical Mass provides the perfect ratio of phosphorous to potassium for this period of development.
How to use
Soil & Pots Mixes
Use from week 4 (day 22) of the flowering period until fully mature and ripe.
Dilute at 0.5ml – 1.0ml per litre of nutrient solution.
For ripening heavy flower & fruit seeds in last weeks (before flush) increase dose up to 1.5ml/L.
Coco & Hydro
Follow as above at, or up to, double strength (max 2ml/L mid flower or 3ml/L to ripen).
Be careful to reduce your base nutrient by 20%, or more, to avoid nutrient burn, especially if using at double strength.
To maximise crop flavour flush using FM Clean Cut and water for 3 – 7 days before harvest.
