I always go via ppm for calmag, bloom nutes and plagron green sensation, for advanced nutrients line up there bang on, i always mix 2m/1L with there lineup.

Concur... Never had to go higher than 2ml/l. And as far as ppms go, i always use ro or rain water so i cant help there. I know that an says it's meant to be used with ro...

Thanks guys. I just peruse google. Looks like tds Meyer just to verify if your water sciurce unknown or you accidentally over fert. Or theres no ml chart etc. just use ro water and follow schedule and tds meter not really needed.

Thanks again
