Hi people. sort all the problems i needed to do. Iv done a complete res change, now im using 40ml part A and part B of canna aqua vega per 20L of rain water, decided to not use tap. tested PH after the whole mixing lark and added my ph drops and the colour turns darkish yellow what reads 5.7-5.9. I done all this 2 days ago on the 30/05/2012 and i wanna post a video what was taken the same day, but dont see alot of growth from the very first pic i posted on the 25/05. if its stressed as we have had a week of hot weather, how long does it take to get back to work. any help would be great and anything else u can see[video] http://youtu.be/HIbb1KvuWP8[/video]

Did you rinse your hydroton before you used it? That looks like dust from your media, not nutes in the bottom of the res. I rinse mine in a colonder

There is a standard rule in hydroponics for nute deficiencies. Change out the solution and make sure your PH pen is calibrated.

Never let your res go for more than seven days. I go 1/6th on what any fert recommends for dirt per gallon of water in my flood and drain table.
