Nute Burn; How To Flush AG

I am pretty sure my plants are suffering from nute burn. Before I joined this forum I threw in a whole tablet and now it's showing to show damage. Doh!

I tried searching for any tips or suggestions. What I did so far is pour out the old water, added new water to rinse out the roots, then added its regular water. No nutes, just water. I will give it 3 days til I add more nutes. I have a 1liter bottle sitting with water and a tablet.

Your plan of action sounds good to me, just make sure your water is ph'd.

2nd day since the flush and I feel she's still getting burned. 2 tomato plants and her drink 20oz of water every 2 days.

Hmm...is there anything I can add to help her or just let time pass? Maybe another flush?
