Ppm of runoff off the charts?!

I just fed my 5 1/2 week old plants that are just recently flipped to flower (2 days ago) and I fed them with ph'd water of 7.0 with a ppm of 850. Checked the runoff and the ph was at 6.1 which makes sense but the ppm was over 2000, my meter maxes out at 2000 and it just flashed at me and shut off lol does this mean I had lots of nutrients still in the soil?? Did I just overfeed the shit out of my plants? The watering they got previous to this was with tap water and I flushed my plants out because of nutrient burn from the last feeding before I got the tds/ph meter and the water going in was the same as it was coming out so I thought I got the nutrients out of the soil? Why are they so high now? Or am I making a big deal out of nothing? I do that sometimes.

If they were suffering from nute burn, and you just gave them one plain water feeding that's not enough to flush the salt build up out of the soil. If they don't get any worse nute burn wise, I would back off the food and just give water until the ppm runoff comes down. Or you can ph the water and do a thorough flush . Did you add monster bloom or Kool bloom, etc. to jump start flowering?

Do not do a flush with ph'ed water. Last thing u need is all the down buffer it takes to adjust15 galls of water to b in your soil. The water will evaporate but the buffer will remain. Don't just take people word... Do your homework

A watering feed does not flush, a flush is 3 to 5 gals of water for every gal of medium

Prophets right about too much buffer solution, if your ph isn't too far out of a good range I would skip it, I mainly deal with hydro where ph is critical.

Thanks for all the responses guys, I didn't mean that last time I just did a normal water with plain water I meant I put 3 gallons of water thru them (they were in 1 gal pots at the time) and then I let them dry out again completely before feeding again, sorry I should have been more clear. I kept putting water thru them till the ppm going coming out was the same as going in which I thought meant that there was noting left in the soil? Correct me if I'm wrong. I guess ill have to just keep an eye on them the next couple days. And no I also didn't add any bloom boosters.

Feed, plain water, plain water until you learn what your plants can take. Its a foolproof method.

Joe blow I agree completely now lol, I bet you it was just a case of my local hydro store knowin that I'm a noob and selling me anything and everything they could and me not knowing any better I bought it. From now on plain water is all I'm gonna give them. Luckily this is just a practise run with some bag seed and I gotta say I'm glad Im doing that, im learning alot! Another question I have now is because so many of my leaves are already burnt from too much nutes, how will I know if they start to go deficient if I keep feeding with plain water for a while? Burn and deficiencies look the same no?
