Dates dont matter, guy offers u no advice on growing then casts doubt on what I gave you.
He says it confusing, for him maybe.
So he decides to pass that confusion onto you.
I only give advise on what im doing/done myself, not what i heard, read or someone told me.
Currently have 2 crops in flower, One @ 5 weeks the other @ 1 week Im at ec around 2.1 thats 1400ppm.
My advice is current of today.
