Identifiy the problem

[Zandor]

the ph rises due to uptake of CO2. The water is the limiting factor. The plants do not discharge into the water.

Maybe we are not talking about the same thing Gen.

Plants do discharge unused nutrients and by-products back into the water. That is why the PPM is only accurate at the time it's mixed. After a few hours with the plants it will start to change. Another reason why you change your res every 5-10 day's.

Zandor Reviewed by Zandor on 04-02-2006. Identifiy the problem ~800 PPM CalMag + FloraNova Grow PH @ 5.6-5.8 at all times -- Skunk #1 -- These are clones under @ a little over two weeks of vegging - I did find algae in the res, so I changed nute solutions last night -- They are under 18/6 cycle -- Plants are getting progressively worse as time goes by. This seems to mainly effect the fan leaves... Rating: 5
