Features

WHEN TO TEST FOR PH: If the pH is off, you may see leaf discolouration as well as reduced growth which may indicate excessively acidic conditions

HOW TO KNOW WHEN TO INCREASE PH LEVELS: It is important to raise your pH levels when there is a nutrient lockdown. This shows itself by making your plant roots unable to absorb the nutrient you feed it so your plants may experience leaf burn and discoloration because although you are feeding them essential nutrient, they are unable to absorb them.

HOW TO FIX YOUR PH: Using a pH meter, determine you pH level. An indication of low pH will require a water flush with pH up to raise the pH levels.

SAFELY RAISES PH: The most important part of the MICROBE LIFE pH UP is that it will safely raise pH levels in nutrient solutions and will never harm plants which means you can rest assured knowing you will have a safe and successful grow.
