PlantBoxer is correct; I know those ferts DO contain some sort of surfactant for foliar application.
7.0 is NOT the pH for hydroponics.
Hydro nutes can be found at any good grow shop, or mail-ordered from an online store. PLEASE use Google; it's the beauty of the internet.... :wtf:

I hope that everyone on this thread telling you that what you are doing is NOT going to work will push you to fix it before your plants die. You need to do a lot of reading; check the 'grow log' or 'hydroponics' section for logs and instructions.
stinkyattic Reviewed by stinkyattic on . Anyone seen this before? This is a small 2gallon hydroponics container and every 3 to5 days it gets this white chalky stuff at the bottom of the bubble stone! Not sure what it is and have never seen it anywhere else. I use well water and my friend thinks it's calcium settlin at the bottom! I also have another question for you, why do they look like this! What is this brown crap, I don't like my girls looking all busted up. Rating: 5
