Apparently Jacks has a Bloom feed & a Bloom Pro feed and they both have the exact same NPK of 10-30-20

So does anyone know what the difference is? This website specifically notifies you they are different products.



Are these supposed to be ran towards the end of flower as a PK Booster on top of Jacks 321 recipe?

They are basically the same. Jacks Nutrients is made for cannabis and hemp but it's based off of the old Jacks Professional Bloom Booster for professional greenhouse crop production for whole sale flowers and vegetables. The hemp formula just has a little bit of sulfur in it. You absolutely wouldn't notice a difference using either of their bloom boosters. Here you can click and zoom in on the label to compare the "recipe" https://www.jacksnutrients.com/online-store/10-30-20-Bloom-p101272610 vs https://www.jrpeters.com/10-30-20-blossom-booster

Just re checked those Fertilizer labels. The JR Peters Professional has Magnesium and no Sulfur, the Jacks nutrients has Sulfur, and double the zinc, iron, etc but less magnesium (that's why the schedule says use 1 gram epsom salt per gallon), I am glad I saw this because I have a 25 pound bag of the professional so I probably don't need to use epsom salt for the first two weeks of flower

Ahh ok, thanks for that clarification. I'll pick up a bag of the Jacks Bloom soon so I have it ready.

So I don't want to use the Cal/Nit Jacks Part B with their Bloom formula?

Nope, that would be too much Nitrogen. The first two weeks of flower you use the bloom for phosphorus. week 3 and 4 switch back to Part A/B. week 5 and 6 & 7 use Jacks finish for Potassium week 8 flush. That's according to the schedule 3-2-1 https://5efb2711-22d2-46e2-827b-2f8...d/3230c0_15310ae79d9b4e3cac50947c616d07f9.pdf (by the way

the bloom still has 10% nitrogen so 5.67 grams in a gallon gives you 150 PPM Nitrogen. Now, your Nitrogen is still there but with the bloom it's now getting a lot more ppm phosphorus, when you switch over to the finish you're still getting 100 ppm Nitrogen but a lot more ppm potassium. If you were to try to get those ppms of phosphorus and potassium with part A and B the Nitrogen would be way too high, it's already 200 ppm N with the 3-2-1 but the P and K lvls are much lower. Amazon has a 25 pound bag of the professional bloom w/ free shipping for $65, it will last years. the jacks bloom on their site is $65 with $20 shipping
