nutes ppm question

[me myyself and I]

hey all, Im have'n a heck of a time try'n to find out what the ppm should be using tiger bloom? right now im at about 1020ppm. about 6 weeks in now. and the one in veg about 1000ppm. using a kinda dwc setup but with a submergable pump in a bucket instead of air stones, been working great so far too. do my ppm reading sound about right?
thanks

Once I hit 1000 ppm's I increase nutes very slowly and watch plants very carefully unless I know the strain. Some strains I've grown 1000 is all they could comfortably take.
