Just Flushed and I have a question

[Cloud]

Do i still need to use hydroguard during the flush?

Hey Cloud, no you don't, But hydrogard might save you a little water.

No, You don't need to do anything to the water.
You can add a flushing agent like Florakleen or Sledgehammer, but that's all that would be recommended.

Also, during a final flush, you should no longer be concerned about pH and you should not adjust the pH.

Sweet thanks for the quick response and i did ph the water lol but oh well im sure it will be ok.

Yeah, not the end of the world, but no need to continue to. pH adjustments are done to help the plant adsorb nutrients - during the final flush you no longer want the roots taking up nutes! Furthermore, "up" and "down" are actually taken up by the plant, so it isn't a complete flush.
But, yeah - I think most growers do it, and it isn't a big deal if you do, just totally unnecessary.
