Flora-nova grow/bloom ppm reading

hi guys

i recently bought a EC/ppm meter. after looking online i found that GH should be measured on a PPM500 scale. i set my bluelab pen to that.

I mixed a batch of feed @ 3ml/Liter. ( max is 3.75ml/ Liter)
this is putting my PPM in the 1900-2000ppm range.
which to my understanding is really HOT.
i have been using these nutes for a few grows. but never had a meter.

so i am not too sure what to make of it.

I am on well water and it PPMs @ 350.

i found a chart for a drain to waste system which i what i am doing (100% perlite hempys)

the chart shows very diffrent mix ratios.
at 5ml/gal which converts to 1.32ml/L

drastic diffrence for what i have been using.

can someone help me make sense of all this?
 
my tapwater is 45ppm

8ml/g in tap water is coming out at 1000 ppm, give or take a few points obv.

Im still a newbie, so not sure what you mean by the 500ppm scale. I used calibration solution to calibrate my tds pen and usually check/calibrate it once a month.
 
If I understand correctly.
You mix at 8mil per gal. Then top the rez up with PH’d water until I have added back the amount of the rez? Essentially diluting it over time. ?

i've done dtw hempys and now waterfarms.

i feed extremely lightly once a day. with well water of EC 0.2 ish, i feed about 0.8 EC total. or 0.6EC of just nutes (300ppm). at most i go up to 1.2 EC total

lucas formula can be done either way: top off with just water or top off with lucas ratio nutes. it's really more important of what the NPK ratio is for it: it's good if not great for cannabis. and simple too.

Ok thank you. I am in mid flower so I think I will go to 8ml/gal and see what happens.

Also when adding booster/additives sucks and liquid koolbloom and floral nectar, and bud candy. Wood you reduce your “bloom” to keep the EC/ppm in spec?

i use nothing but nutes (GH maxi bloom) and a kelp/humic mix. silica every other week. that's it for me.

If you are working off the chart i beli3ve they us ml meaurements against gallons. IE - 2.5ml per US gallon, which equals 3.79 litres.
