I dont see the result in Desired formulation page. All the ppm value changes to 0. Also i have selected 3 ml per liter.<br /><br />Please let me know if i am doing any mistake here.<br /><br />--RaursUnknownhttps://www.blogger.com/profile/08369079851794025522noreply@blogger.comtag:blogger.com,1999:blog-5344600017978004199.post-35936534050608146882010-09-15T14:21:21.093-07:002010-09-15T14:21:21.093-07:00Hello John,

If you have potassium hydroxide flakes then leave the 100 within the purity box. In the case of phosphoric acid use input the strength as w/w% on the box so if you have 50% phosphoric acid, input 50. I hope this answers your question :o)<br /><br />Best regards,<br /><br />DanielDanielhttps://www.blogger.com/profile/00940108413648645894noreply@blogger.comtag:blogger.com,1999:blog-5344600017978004199.post-3401127754613582632010-09-15T14:14:29.818-07:002010-09-15T14:14:29.818-07:00Daniel, within yor calculator it has a check box f...Daniel, within yor calculator it has a check box for potassium hydroxide. I have potassium hydroxide flakes 100%. Is this what is listed or is it some solution of a lesser strength of potassium hydroxide?<br />Also there is verying strengths of phosphoric acid, which strength is it that is within your calculator?<br />sincere thanks -JohnUnknownhttps://www.blogger.com/profile/05992719213035187810noreply@blogger.comtag:blogger.com,1999:blog-5344600017978004199.post-20603409534119028702010-09-12T15:59:10.845-07:002010-09-12T15:59:10.845-07:00Hi,

I found a web page about the solubility of various fertilizer salts. <br /><br />http://www.smart-fertilizer.com/articles/fertilizer-solubility<br /><br />The MPK that I am attempting to dissolve is soluble at a rate of 180 grams per liter at 10 degrees C. At 20 degrees C it is soluble at 230 grams per liter. I can either warm my solution or use more distilled water. <br /><br />Instead of making 5 gallon batch I will make an 8 gallon batch (4 gallons A + 4 gallons B), which should solve my problem.SkizNiphttps://www.blogger.com/profile/17264227557326164712noreply@blogger.comtag:blogger.com,1999:blog-5344600017978004199.post-2088669571621758792010-09-11T22:01:13.995-07:002010-09-11T22:01:13.995-07:00Thanks for helping me Daniel.

Am I using too little water?<br /><br />Thanks!SkizNiphttps://www.blogger.com/profile/17264227557326164712noreply@blogger.comtag:blogger.com,1999:blog-5344600017978004199.post-84128236097866880062010-09-11T04:02:23.442-07:002010-09-11T04:02:23.442-07:00Hello,

I would doubt the quality of the salt you currently have, you can buy a small quantity from another supplier and compare it to see if you got the right salt. I hope this helps !<br /><br />Best Regards,<br /><br />DanielDanielhttps://www.blogger.com/profile/00940108413648645894noreply@blogger.comtag:blogger.com,1999:blog-5344600017978004199.post-83697158040775997142010-09-10T22:30:10.314-07:002010-09-10T22:30:10.314-07:00I am making my first batch of hydroponic fertilize...I am making my first batch of hydroponic fertilizer. I have a two part formula and I am finished with the A part. I am now attempting to dissolve some monopotassium phosphate in some distilled water, but it is just sitting on the bottom of the bucket Im mixing it in. It isnt dissolving. Everything I read about this stuff says it is highly soluble. Do I need to use boiling water?SkizNiphttps://www.blogger.com/profile/17264227557326164712noreply@blogger.com
