Bloom Booster Fertilizing - Help

Hi

In 3rd week of flower. Been using Jacks 321.

I thought I read you can use Jacks 321 from start to finish? But, I’m also reading about bloom booster during flowering?

I see Jacks has a bloom fertilizer. Is that meant to be added to my current mix (an addition)? Or, is it meant to replace my current mix?

Any help with understanding would be appreciated

  • Seed: Do-si-dos, Photo, from ILGM
  • Vessel: Coco + Perlite, 5 gal fabric pot
  • Nutrition: Jacks 321 + Silica
  • PH of Water: 60 - 65 (do not test runoff or ppm)
  • Environment: Outdoor
  • Location: Southern US, hot and humid
  • Temps: Upper 80s to 90s

The jacks bloom nutrients are a stand alone nutrient with epson and part B added. I use it for the 1st 3 weeks of flower then back to 321 with jacks finish weeks 7-9 and water feed only the last 2 weeks :love_you_gesture:
