Hey, buddy! π
I checked out your diary and figured it out. π You have a phosphorus deficiency, on top of an overdose of nitrogen; not only did this deficiency show up by week 2 in the photo from 30.06, but on 06.07 you had a terrible nitrogen overdose with the Gro additive! π
You've got everything happening at once here, bro! There's also a phosphorus overdose coming in a day; you're giving way too many nutrients, man! For veg, stick to a 1:1 ratio of Grow:Bloom, but not at the doses you've been giving!!!! Cut both additives by half!!! π
Make your soil pH 6.3!!! π
Do the additives:
-starR - 2ml/l
-A - 1.5ml/l
-B - 1.5ml/l
Good luck, bro! βπ
