Very easy to over feed with that trio from my experiences, wicked potent stuff....mix WEAKish...
I sucked bigtime during the "Hand watering Coco trials."
The constant fear of overwatering/feeding, led to salt buildups, leading to lockout, leading to appearance of deficiencies, leading to overwatering/feeding, leading to toxicity, leading to casualties.....
That was a rough two weeks.....
