Blumats and elemental ppm values

Is anybody using this combo?. Having difficulty finding a working ppm value/ratio.

I've asked some questions over the months to get a better understanding on elemental ppms and settled with this as a ''water to run off'' value.

N - 150 (reduces late flower by lowering calN)
P - 38/60/84 (mono potassium boost)
K - 160/189/216 (mono boost)
C - 95
M - 60
S - 65

From the site below the individual ppm values are as close as I can get them, the values in that link are, unless the info is outdated, a minimum guideline for healthy mj.

If the above is correct how would you apply that to blumats with no run off?.

read the plants, not the run off

With all respect run off ppm has little to do with the question. This is more about build up salt/ppm from what is going in.

Let me get my popcorn while awaiting @xtsho

I use Blumats and run a nutrient regiment of about 1/3 called for values.

But if that is 1/3 of liquid nutrients that are not based on elemental ppm it won't help me much, is the problem.

Don't worry about elemental ppm's. Just run 1/2 strength nutes "or less" and call it a day. The thing with blumats is the simplicity and ease of use. You're making it harder than it needs to be. Fill the reservoir and walk away. It's that simple.

And since there is no runoff blumats work best with a substance like coco. I recommend 100%. You don't need any perlite. Feeding less is better. I've never had any issue with salt buildup but I never go much over 800 ppm. Coco and blumats is a very hands off method of irrigating your plants. Four plants and an 18 gallon reservoir and you're good for a long time.

I’m growing 6 plants and run a 3 gallon reservoir that is refilled weekly. Wasn’t until about week 5 of flower that I needed to go to 6 gallons a week, two 3 gallon mixes.

I like 3 gallon reservoir in case of leak bys, which I did have one this go around.

I appreciate the time you've took but I don't wish to wing it any more than needs be, if somebody has already found a working elemental ppm value then I'd like to know it. For example ''or less'' is vague and the difference of a deficiency. I ran 1 tester on blumats and all was fine until week 5, then not so fine, growth slowed with some lock out or burn while the rest continued. Shame, it was feeding heavier and had a much wider stem even at the end. That was going at ''half'' of my normal strength, so I came to learn that my normal strength was higher than needs be. If I had of went full tilt and winged it like you suggest, it would have been a disaster. I won't run more than one of these till it's figured out, the quicker that is figured out the better, to go all in. It's why this thread is up. It's fine if you don't have a solid answer.

Yes people say ''just read the plant'' and I agree to a point, but I don't think that scrutinising the elemental ppm/ratio of what is going in is a bad thing at all, in combination of better understanding what minimum values are required for health. Surely the better you do that results in less need to read negative reactions.
