hello

first week of veg was good was abit slow growt had ec on 0.4, 280 ppm so i thought i needed to give more nutes...but the problem was my ec-meter wasnt calibrated so i gave too much from the start of and when i gave more i burned them... now i got a new ec/ppm meter when i checked the res. with the new meter it was 1.2 ec , 840 ppm..so i lowered it to abit under 0.8 ec and a few days after i change the res. now the res. is at 0.83 ec/581 ppm, s
but still thers some burning on the edges of leafs wondering if im still abit high on nutes or if its the ghe nutrients that r low on mg?

seams to be related to the tap your using, is that 581 with the nutes or without?
if its with the nutes then add some more make it 650ish... they look like there short on mag/cal/nitrogen, add a little epsom salt or mag/cal solution and think about a foliar of somthing nitrogen based. assuming you can.

hey digital.... its 581 with nutes...got very soft water here...i use the ghe 3 part its little mg in it compared to advanced nutrients 3 part so i added som epsom yesterday

I would add some magnesium and give them some time to recover and keep the ppms to where you are at right now, the damage will stay regardless and will eventually die....
