This flush thing is getting out of hand. Im gonna answer this one last time and i hope i dont hear about any more lol. I water with PH'd water ever 3rd watering. For the last 10 days i give my plants straight PH'd water and I flush with Flora Kleen. Im getting allmost 3lb per 1000w light. If im doing something wrong please let me know what i can do to correct this. I know my plants might not get the flush the really need sometimes but there is no way I will soak my beds so much that the water runs out the bottem.

I know that a final flush can be done because in that case you are just not providing any nutes so the plant will use all the stored ones up, so that no one is smoking nutes.
