Alright thanks mate!

I shuld add the phosphoric acid after the nutes, right?

edit;

Oh i totally forgot to mention that i just transplanted the plant from a really small pot to this red bucket, with plenty of new soil (like, really alot more).

Its only been a day, perhaps i shuld wait and see if the plant takes up the new nutes from the new soil?
