I'm probably gonna use mostly sulfates for my micros... I'm a little bit afraid to smoke ethyl whatever acetate.

Hey... forgot to ask... can you plug those values (post #113) into hydrobuddy and see what it returns.

Sweet... gonna probably order some nitrogen and phosphorous tonight. I can then hit any target.

Doh... it was my fault... I input 0.203475 instead of 2.03475 on the grams (can't do math in my head for some reason)... new values from your sheet are N 151 (not sure why this is so much higher than mine) P 8 = 18.3 P2O5 K 95 = 114K2O Ca 122 Mg 61 S 70 so values are pretty close to what I figured

Well I just entered 1.5t FloraMicro, 1t FloraGro, 1/32t FloraBloom and 2034.75mg MgSO4... the values I come up with are N 124ppm P2O5 15 K2O 99 Ca 97.7 Mg 60 S 70 Your calc is returning N 151ppm P 8 = 18.3 P2O5 K 95 = 114 K2O Ca 122 Mg 14 S 7.4 Something is amiss... is that 26 and 34 under Mg...

Almost forgot... where's the best place to order nitrogen and phosphorous chems from... I've got all the chems I need except for nitrogen and phosphorous.

Had to lower P2O5 all the way down to 15ppm but looking better now. Renfro I'll try inputting something I've already calculated and see if it gives me similar values or not.

G/Gal is that grams per gallon? You may want to use milligrams if it is since most quantities are very small.

You just said it all... confusing. They should have a standard but who is going to take the time to clean up the fertilizer industry. I think Renfro would make a better teacher than I for learning xls but it's really fairly simple. If you want the cell to equal the sum of cells A1 and B1 you...

Looks pretty decent... scrolled right on me just fine using Excel 2016 on Windows 10. If it's giving you values that seem correct then should be good to go. I made one that gives me volume of each chemical for easy measuring... well I input a volume and it calculates ppm for me.

Hey as long as you know which it refers too all good... just saying when you talk with others it can be confusing due to current standards. The labels on my Flora series GenHydro nutes all list phosphate (P2O5) and potash (K2O) and since all lab work I get done returns P2O5 and K2O I've just...

I never know if P and K refer to actual P and K or to P2O5 and K2O. It looks like the P in your charts refers to P2O5 and K to K2O (at least for GenHydro)... not sure about the others but you should make a point to designate P or P2O5 and K or K2O as there is a large difference (Manufacturers...

Sounds easy enough... lime and peat reactions can be difficult to predict from what I hear though. The pH will still be changing a month after you mix it up so give it some time to "get right". Then there's the matter of nutrient concentrations and dealing with denitrification but since you're...

I downloaded HydroBuddy but haven't learned to use it yet... I'm still plug and chug with the Casio for most of my calculations. Your micros look pretty good as far as I know... here's what I'm targeting Fe 0.3-3 Mn 0.1-3 Zn 0.1-2 Cu 0.05-0.5 B 0.05-0.5 Mo 0.01-0.2 Na 0-150 Cl 0-100 These are...

I'm just getting into mixing but I must admit the best results I ever got using chemical fertilizer was with a fertilizer created for feeding with every watering. I was growing in soilless and the fertilizer was a Miracle Grow product (I think... been a while). You added like 10 drops per...

I'd love to see the ppm numbers you finally settled on for that grow.

It can be done but you would need a laboratory to analyze each organic amendment for percent composition of plant essential nutrient. The agricultural dept. can usually do this for a low fee. In soil micronutrients are usually not a problem... in soilless though you would need to amend the...
