Anyone ever Go Up To 3500PPM????

Anyone out there have experience with taking there rez up to 3500 PPM? Have been dealing with bone heads, I think, that are saying 3 week old clones in 2000 ppm then in flower 3500 ppm. Want only people that have done it. Also if you have the opinion that it is suicide for plants, please say you agree with me that it is much to high for any hydro system and or strain... Thanks....

I'll choose to quote Ralph Wiggum, who said:

"It tastes like... burneding..."

well i think you can go over your regular ppms for a short amount of time..then flush it out..i think the most ive ever used is 2500 hit it a few times then flushed
