Application pH- Grow pH- Grow has been designed to regualte the acidity during the growth period up to one week into the flowering period. 8.4% Nitrate nitrogen (NO3-N), Specific gravity 1,24 Kg/l. Application pH- Bloom pH- Bloom has been designed to regulate the acidity during the flowering period. It contains Phosphprus for better flower formation. 42,7% Phosphoric acid anhidryde (P2O5), Specific Gravity 1.42 Kg/l. With the right adjustment of the pH, the main and trace elements can be absorbed by the plant more easily. Dose: Ready for Use Instructions: In order to adjust the pH, add pH- 1ml at a time [ 10ml for 200l solution tank ], have the water circulate well, check pH value. Repeat until the correct pH has been obtained: Soil [ 5.6 - 6.7 ], Hydro/Cocco [ 5.7 - 6.4 ]
