Koolbloom is .25 a tsp=teaspoon to a gal...which is 17.5 tsp...or 5.8 tbsp...tbsp=tablespoon
me...in your shoes I'd keep it around 4 tbsp tops...again without knowing your EC kinda pointless. Seaweed always helps...but should be used throughout the LIFE of the plant.
Add your base nutes to rez...measure EC....
Add Raw,
calmag, silica...measure EC
Add koolbloom by single tbsp...measure EC after each tbsp...when finished --->
ADJUST PH NOW!!!
You act as if you're on the brink of failure, if the buds are hard and are gaining size, have aroma youll probably be in good shape....but in the future get a strong grip on your EC.
