Crispy brown leaves

Hey pal. After growing some fastbuds and looking thru diaries and also reading your diary you aren't giving enough of cal mag as you are giving everything else 2ml per l of strong marco nutes but on trace nutes you are giving 0.3 which 2ml alone in some cases isn't enough as these are only trace elements in your cal mag it'll only be like 3-4% and even less on mg and other micro nutes. It's very hard to get cal mag/micro nute toxs. Focus on micro nutes and push your ml up to 2ml/l of cal mag and even higher as the grow moves on. Chill out on the grow for now as some leafs are looking like they also have some light N tox. Very green shiny leafs. I might be wrong as pics are dif when the lights on or flash. Good luck pal.
