Rob from Paso Robles, Ca writes
I plan on running a drip system, 75 plants, @ 2.5 gallons of water for each plant, each day. The plants are in a sunny area in central CA. I would like to add the fertilizer once a week (strong dosage). The 500 gallon container will be topped off with water every other day and stirred every hour on the hour. We are a medical farm 420 If you could give me a range to work with and or start with that would be great. What product would I use during flowering
How much of a fertilizer such as the Peters Professional 20-20-20 General Purpose Fertilizer that you use will depend upon the amount of the nutrients (usually Nitrogen) you want to apply to your target plants. Please refer to the product label for complete nutrient rates. We would suggest you speak with a Master Gardener or your local Department of Agriculture for recommendations for your situation as we are not plant experts. You may also contact Everris, the manufacturer, for further information at 800-492-8255.
