TROUBLESHOOTING FACTORS TO CONSIDER
Arid, bright, hot environments cause plants to drink more than if they are grown where it’s humid, dim and cool. Thus gardeners should use less concentrated nutrient solutions when growing conditions are more intense in order to lessen the risk of overfeeding.
The pH (acidity or alkalinity) of a nutrient solution affects the availability of the elements contained within. Use GH pH adjusters to maintain nutrient pH between 5.5-6.5
