Here’s how I handle Jacks. I don’t use their Bloom product, but do use a monopotassium phosphorus (MKP) based fertilizer during the transition from veg to flower. Feeding ratios adapted from the honorable @Nicky
Jack’s 321 standard mix & used for veg= 3.6/2.4/1.2
Booster mix= Jacks Part A/ Cal nitrate (Part B) / Epsom salts / MKP
You can adjust your feed. @Graysin’s recipe is wonderful. I also incorporate Fox Farm Dry Boosters (Open Sesame, Beastie Bloomz, and Cha Ching) at about ½ strength. My PPM’S, with Silica Blast added first, fall at almost exactly 1,150 and pH falls just around 6.35 (starts at 7.7 from tap). With Jack’s 321, if you can get the ratios right, there isn’t a whole lot of need for boosters. Mad trich production. Steady, healthy growth. I’ve seen some even go double strength and still not burn up a plant. Sorry if none of this answered your question.
Hello and thanks for taking the time to provide the info.
I “think” that since I am a one plant at a time grower, I’ll stick with just jacks 321 through harvest.
As i get more into this hobby, I may get more detailed with my fertilizer.
Funny when I think about it….I started this hobby by thinking I’d just plant a seed and see what it does. Since then I’ve learned about soil (and coco) and nutrients and PH, photo vs auto and so much more. My head is spinning trying to add in more when I’m just a single plant grower….for now.
