ONLY 1000 PPM? And yes, it is nute burn.

Which meter are you using? Different companies use different conversion factors, U.S vs Europe

That's the 0.5 scale, so your PPMs aren't lower than they might be (if it had been the 0.7 scale, for example).
I think 1000ppm is pretty high.
You can check your calibration by putting 1g table salt in 1 liter of distilled water. That produces 1000ppm.

I do a living organic soil now, so its been a while since I have used mine. I have a Hannah and I think that it has the .7 conversion???
Hanna is typically 0.5, but they do other scales too. So, it's confusing when people refer to the "hanna scale" (0.5).
The meter he pictured is HM and it is, without a doubt, 0.5 scale.

I almost took a pic of my PH meter, it is covered in dust! You are probably right. Notice I used a lot of??? I just wanted to bring up the topic really

Guess i dont understand...shouldnt 1000ppm be 1000ppm?
I don't understand it either. But, there are 3 scales (plus EC). See this chart. If you were using the other scales, then 1000ppm might be like 700ppm (the more common?) scale.
But, you're definitely the 0.5 "Hanna scale." (But, don't forget, Hanna makes meters using the other scales. So, never assume a Hanna meter is "the Hanna scale."). We'll all laugh about this some day.
I fed 1000-1200 in late flower using GH Flora 3 part. That's the highest I've ever done. I typically feed 500-700 (counting the 150ppm in the tap water). So, it's hard to know if you're overfeeding. I guess it depends on the nutes, how they're formulated.

I use either the 3 part gh following the scheduled on the floraSeries Performance pack (only for the 3 part not the additives) with 3ml per gallon of armorSi or the maxiBloom dry at 5g per gallon with 3ml per gallon of the micro from the 3 part and 3ml per gallon of the armorSi in a 32 gallon res with the flow and grow setup using only 6 of the 2 or 2.5 gallon (cant remember) pots
