<span class="link_user">@Gabriel_OD</span>, You are welcome :hearts: Take your time, I did the same when I asked questions. P.h. meter is definitly the key. First mesure your solution p.h. (with or without nutrients) then the run-off gives you a good idea, if you mesure a too big difference them, then you have an issue. :hearts::relaxed::hearts:I will follow your diary ;)

<span class="link_user">@Blabina</span>, thank you very much for coming all this way to check my diary. (I forget to tag my diary in grow question). I will check your answer and all other answers. As for pH, I still dont have one atm. I will go buy one soon.
