Hey, buddy! π
I checked out your diary and found out. π You have a nitrogen overdose! It showed up already in week 2 in the first photo + the heat made the leaf tips curl up. The next weeks 3 and 4 also have the same nitrogen overdose, with the Gro additive! π
For veg, keep the ratio 1:1 Grow:Bloom but not at the doses you were giving!!!! Half the amount of both additives!!! π
Make the pH of your soil 6.3 pH!!! π
Use these additives:
-micro - 2 ml/l
-gro - 1.6 ml/l
-blom - 2 ml/l
Good luck, bro! βπ
