Hi @PremiumBudsEU and thanks for the reply, really appreciate it.
Thats exactly what I've been trying for the past two days. (The plants are actually on day 57, today 6/1/2022 - haven't uploaded everything yet) Made a new lighter feed mix and ending EC was 1.3
So can't really tell if the tip/margin burn still continues, but for sure the leaves are now losing the green shades which happens IMO interveinal. And that would prob indicate in Magnesium def (they only getting about 35ppm of Mg now as lowered Remo nutes down to 1ml/L and everything in 1:1)
I knew Mg def could show up as theres only 1ml/L CalMag. And can't rise the Mg ppms much as it will then block Ca..
And then if I'd up only CalMag dose to 1.5-2ml/L then the whole mix heavily N based.
I'll try to upload the rest of the pics later today to show up how it looks now.
Lol these are for sure the hardest phenos I've grown. Well just gotta keep tryin π
