I've been doing a lot of reading up here in the forum about lucas formula and decided to go with it, its just that i can't quite make sense of somethings, I've use the metric system so bare with me, i have the complete line with GH the triple one, micro, grow and bloom and following recommendations its 30ml between the 3 for grown plants, i use coco so its not the original lucas formula, i just made a batch of 10 liters roughly 2,5 US gallons and its 6ml micro and 9ml bloom each gallon, 10 liters thats about 15 ml micro and 22 ml bloom with adds up to 37 ml of nutes instead of 30 if u use all 3 ones, so following the recommendations lands me at about 1600 ppm, and so does the lucas formula, i just don't get it i read that the ppm for the lucas formula for coco 6/9 should be much lower, and shouldn't 37ml of nutes have a higher ppm then 30ml of the exact same line of nutes? give or take. my tap water is about 200 ppm and the ppm meter is calibrated. I've followed the recommendations for a little over a month and i saw what i think was a little bit of nuteburn on 3 of the plants so i figured i go with the lucas formula to avoid complication and nuteburn. does anyone have any thoughts about this why its so high ppm readings, what I'm i doing wrong? what shall i do? just as an example cuz I'm mixing nuts right now preparing to feed my ladies, 6ml of micro in a gallon puts me up to 900ppm, according to what i read it should be a lot less. any help is highly appreciated!!!
