I suppose I keep loosing sight of the propterties of DWC style cultivation.

The changes in pH and EC are constant variables and demand attention.

I have been quite used to growing in potted coco media and taking EC levels to the max... The signs of over fert come on much slower with soil. Hydro is very much unforgiving to those who do not apply their full attention to their work. but I can see that the rewards can be quite generous.

I've also lost sight of the fact that I'm currently farming very small plants. Some of those small plants are less than one-fith the size of plants that are normally grown, so I should have been bearing in mind that the transportation of nute to the plants vital areas will be quick in comparrison to 4-5 ft tall potted plants... I'm ready to give it another shot, but next time I'll employ factors that will stop over fert problems... ~(over fert seems to be my only major fault, apart from not switching the pump on sometimes for over a day)...
