A full base and strength line, with no stage bottles.
Cutting Edge runs a liquid 3-part base, dry Louder Powder bases and a strong set of supporting additives: cal-mag, silica, carbs, traces and a brewed tea. What their list doesn’t have is one bottle per stage of the crop. That’s where Pre, Ultra, Phat, Ooze and Final go, on top of the base you already mix.
- Stays as is: Micro, Grow and Bloom (Cutting Edge Solutions), Louder Powder, Ascent and the pH line.
- Both have one: cal-mag, silica, carbs, traces, humic and kelp. Run one, or test them side by side.
- Not on their list: stage additives for mid veg, the flip, mid flower, late flower and the finish.
Their line, Bloom’s fit at a glance
Matched on job, not NPK. Cutting Edge prints rates per US gallon, Bloom per litre on a weekly feed chart. Tap a tag to filter.
Keep your base. Bloom’s additives sit on top of it.
Keep the dry base. Bloom’s additives are liquid and run alongside it.
Their Elemental line for amended soil stays as it is.
Bloom doesn’t make pH adjusters, so these stay.
Same job. Theirs can split Ca and Mg into two bottles. Pick one plan.
Both go in first. Sodium silicate on theirs, potassium silicate on Bloom’s. Run one.
Both put carbohydrates and potassium in the tank. Theirs is flower only, SWTNR starts in veg.
Both top up minor elements. Theirs leads with potassium and iron, Sea Minerals is from sea water.
Shared humic and kelp ground. HumTea is brewed for 72 hours; Bloom’s are ready-to-pour liquids.
Both spray in veg and the flip. Theirs are root-feed bottles with a foliar rate; Bloom’s are spray-only.
Their liquid base steps from Grow to Bloom at transition. These add a stage job there.
Phat in flower weeks 3 and 4, Ooze from week 5 through the flush, Final over the last two weeks.
Tuna and kelp tonic that runs alongside a mineral base.
Amino acids, B vitamins and fulvic acid from cuttings through flower.
Why each one fits
What the Bloom product does, the research behind that kind of input, and where it sits in a program that already runs.
One bottle for each step
What it does. Pre in mid veg (weeks 2–3), Ultra at the flip (flower weeks 1–2), Phat in flower weeks 3 and 4. 1 ml/L, 1 ml/L and 2.5 ml/L, weekly. These are timing tools, so there’s no study cited for them here.
How it stacks. Cutting Edge’s Grow page drops Grow at flowering, and their charts move the base by stage. These sit in those same weeks on top of Micro and Bloom (Cutting Edge Solutions). Our read: check runoff EC when you add anything.
Ooze and Final at the back end
What it does. Ooze is plant extracts, fulvic acid, vitamins and amino acids at 2.5 ml/L weekly, from flower week 5 right through the final flush. Final runs 1 ml/L weekly over the last two weeks, alongside Ooze.
How it stacks. Their Bloom page lists an optional flush at 10 ml/gal, and Cal-Mag Amplified can be cut back in late flower. Ooze and Final go into those late weeks with the base held where it is (our read).
Tuna and kelp in the tank
What it does. Seafuel is tuna and kelp; Seaweed is southern bull kelp. Both run at 1 ml/L weekly: Seaweed from seedling through the flush, Seafuel from clone through late flower, tapering at the flush.
Reviews of seaweed extracts report effects on growth and stress tolerance across many crops. Work on protein hydrolysates, which fish inputs belong to, is newer and links them to nutrient uptake, mostly under stress. None of it tests these bottles or cannabis.
Ali et al. (2021), Plants (review) · Malécange et al. (2023), Int J Mol Sci (review)
How it stacks. HumTea brings kelp in a brewed tea, used weekly or bi-weekly per its page. Seaweed and Seafuel are pour-in liquids, so a grower running the liquid or Louder Powder base can add them without a brewer (our read).
Roots from the cut onwards
What it does. Roots runs at 1 ml/L as a cutting dip, or 0.5 ml/L weekly from cuttings and veg through flower, stopping in the final 1–2 weeks.
How it stacks. Micro’s page sets 2 ml/gal for cuttings and seedlings. Roots goes alongside that first feed, then carries on in the weekly chart (our read).
Where each bottle sits in the cycle

Timing comes from each Cutting Edge product page and their feed chart PDF. Grow stops at flowering. Bloom’s optional flush rate is pale. Cal-Mag Amplified can be reduced or stopped in late flower. Bulletproof SI’s page says through flower week 6, the chart says week 4, so week 5+ is pale. Sugaree SP’s page says week 3 to harvest, the liquid pages just say flower. HumTea is brewed and used weekly or bi-weekly, so it’s pale (our read). Bloom’s bars follow its weekly feed charts; pale Bloom bars are tapers or as-needed bottles.
Put it side by side
Where both ranges have a product for the same job, the fair answer is a test in your own room. Here’s what to watch and how to keep it fair.
Keeping it fair
- Same plants. Clones off the same mother, same cultivar, same age.
- Same room. Same light, climate, media, pot size and watering.
- Same base. Keep the base feed and EC the same on both sides.
- One change. Change only the product being tested, and write down what you see each week.
Where the programs complement each other
Stage bottles in their back end
Late flower on Cutting Edge’s list is Bloom (Cutting Edge Solutions), Sugaree and Uncle John’s, with no stage additive. Ooze from week 5 through the flush and Final over the last two weeks go on top, 2.5 and 1 ml/L weekly.
Kelp, tuna and humic on Louder Powder
Louder Powder is an all-mineral dry base. Seafuel, Seaweed and Humate add tuna, kelp and humic acid at 1–2.5 ml/L weekly. HumTea does a similar job as a brewed tea in their soil line (our read).
Roots next to Micro at the cut
Micro’s page runs 2 ml/gal for cuttings and seedlings. Roots goes on as a 1 ml/L dip, then 0.5 ml/L weekly through flower.

Background, science and sources
Who Cutting Edge Solutions are
Cutting Edge Solutions is an independent, family-owned nutrient maker founded in 2001 by John Piccirilli, known as Uncle John. His nephew Sean Piccirilli is CEO. They started in Santa Rosa, California, moved to White City, Oregon in 2022, and list a team of 25. There’s also a CES Colombia site.
The range is split into families: Base (Micro, Grow, Bloom), Mineral (Louder Powder), Strength (Plant Amp, Mag Amped, Uncle John’s Blend, Cal-Mag Amplified), Advanced Molecular (Sugaree, Sour-Dee, Bulletproof SI), Balance (pH) and Elemental (Ascent and HumTea) for amended and living soil. They sell online, through local stores and distribution partners, to small growers through to large commercial sites, with injection charts for bigger setups.

What each company brings
Cutting Edge Solutions: A liquid 3-part base, dry Louder Powder and Ascent bases, cal-mag and single Ca and Mg bottles, silica, carbohydrate and trace additives, a brewed humic tea, pH adjusters, and reservoir, injection and foliar charts.
Bloom: one additive for each stage of the crop, seaweed, humic and sea mineral inputs, foliar sprays, and weekly feed charts for soil, coco and hydro. Rates and timing are on every product page.
Cropping Solutions, the other brand under Agricultural Organics, isn’t part of this report.
Dose basis: how each side counts
Cutting Edge prints liquid rates in ml per US gallon for reservoirs, injector ratios for bigger setups, and grams per gallon for the powders. Their product pages don’t state how often to feed. At 3.785 L to the gallon, Cal-Mag Amplified at 5 ml/gal is about 1.3 ml/L, Bulletproof SI at 1 ml/gal is about 0.26 ml/L, and Sugaree at 10 ml/gal is about 2.6 ml/L.
Bloom prints ml per litre on a weekly feed chart: Cal-Mag 1 ml/L, Silica 0.33 ml/L and SWTNR 1 ml/L, weekly. Their rates sit on their own charts, so the same number on each side isn’t the same weekly amount.

Rates as printed on each company’s page (1 US gallon is 3.785 L). Bloom’s rates are per litre of nutrient solution, dosed weekly per its feed charts. Pick a product and your tank size.
Silicon and plant stressEmerging
A 2017 editorial in Frontiers in Plant Science introducing a research topic on silicon says it’s widely studied for stress tolerance, but there’s still no conclusive evidence on exactly how it works.
Why it matters here: Bulletproof SI and Bloom Silica are both silicates that go in the tank first. The research backs silicon as worth a look, with open questions, so treat the benefit as emerging.
Deshmukh, Ma and Bélanger (2017), Frontiers in Plant Science (editorial)
Humic substances in the root zoneWell supported
A 2015 review in Scientia Horticulturae links humic and fulvic acids to lateral root growth and to changes in roots and shoots tied to nutrient uptake.
Why it matters here: HumTea lists humic acids and Bloom Humate is 10% humic acid, so both sit on the same body of research. It doesn’t test either product.
