cypo74 Posted March 11 Share Posted March 11 ive just noticed youre in coco, im a soil grower, i know sod all about coco, except it does need to be loaded with cal mag at the start if it isnt pre loaded Id wait for a coco grower to chime in before going to town 1 Link to comment Share on other sites More sharing options...
Shumroom Posted March 11 Share Posted March 11 I don’t have my maths brain in atm, but it looks like you may only require Mono Magnesium to correct the ratio to give 3:1 I reckon that by the time you add the required amount of Magnesium, this will probably bring your water up to 0.4 EC. I’ll pop back later when I’m more awake Or I’m sure a few others have learned how to make the adjustments from a suppliers report Atb 1 Link to comment Share on other sites More sharing options...
Sid the Seedkiller Posted March 11 Author Share Posted March 11 @Shumroom bringing my EC up with Epsom sounds a better idea than cal mag for sure. 1 Link to comment Share on other sites More sharing options...

sweettooth Posted March 11 Share Posted March 11 @Sid the Seedkiller my waters similar, add 2.5g epsom salts per 20L to hot water. (just a bit) shake and then fill up rest of container to normal temps. add silicone, shake well, add alll other nutes, test pH and adjust. I find 4ml of Dutch pro ph down for grow brings me down to 6.2 but I'm using Growers Ark nutes, other nutes and types of pH down may differ, I've started recording more vigorously my measurements and readings so I can return to them rather than guessing 1 Link to comment Share on other sites More sharing options...
Sid the Seedkiller Posted March 11 Author Share Posted March 11 @sweettooth yes mate thats what I'm talking about. I'm using the canna range, although my PH down is Growth Technology, I may switch to Dutch pro as its Nitric and not Phosphoric acid. I'm keeping detailed noted too. Cheers fella.
