Drip Hydro Feeding Schedule: The Complete Feed Chart Explained
Drip Hydro's line is built around six liquid products, Base A, Base B, CaMg, Flex, Flow, and Ooze, each sold at matching Quart, Gallon, and 5-Gallon sizes. This is the actual feed chart: what to run each week, how the products layer on top of each other, and where growers most often get the sequencing wrong.
The 30-Second Answer
- Base A and Base B form the foundation every week, vegetative and flowering alike.
- CaMg runs throughout, at a lighter dose in soil, heavier in coco or hydro.
- Flex steps in once flowering starts, the PK push for bud development.
- Flow and Ooze layer on top in mid-to-late flower for finishing and sweetening.
- Mixing order matters: Base A before Base B, always, to avoid nutrient lockout in the reservoir.
We stock the complete line and can help you dial in the exact week-by-week ratios for your specific medium.
Why the order matters more than the ratios
Base A carries the calcium; Base B carries the phosphates. Concentrated together before dilution, those compounds react and precipitate out of solution, the same reason virtually every 2-part base system on the market keeps A and B separate. Add Base A to your reservoir first, let it fully dissolve and circulate, then add Base B. Everything else, CaMg, Flex, Flow, Ooze, goes in afterward, one product at a time rather than all at once. This sequence matters more than getting any single product's exact dose perfect; a cloudy reservoir from bad mixing order causes more real problems than a slightly-off PPM ever does.
Vegetative stage: Base A + B and CaMg
Through vegetative growth, Base A and Base B form the complete nutritional foundation, ramping from a lighter dose for young plants to full strength as they mature. CaMg runs alongside from the start; coco and hydro growers typically need a heavier CaMg dose than soil growers, since coco naturally binds calcium and magnesium, making less available to the plant than the same feed would deliver in soil.
Early flower: Flex enters the schedule
Once you flip to flowering, Flex PK-Booster joins the base as your phosphorus and potassium push, the input most directly tied to bud site development and density. Start it at a lighter dose in the first one to two weeks of flower while the plant transitions, then move to full strength as flowering establishes. Base A and B continue unchanged through this stage; Flex is additive, not a replacement.
Mid-to-late flower: Flow and Ooze layer in
Flow enters the schedule in mid-to-late flower, rounding out the feed as the plant moves toward peak bud development. Ooze, a plant sweetener and root-zone enhancer, typically comes in during the final two to three weeks, supporting nutrient uptake and microbial activity in the root zone through the home stretch. By this stage you're running the full six-product schedule, Base A, Base B, CaMg, Flex, Flow, and Ooze, before beginning to taper as harvest approaches.

Common mistakes with this schedule
The most common error is running Flex at full strength from day one of flower instead of ramping into it, which can push PK levels higher than a plant still transitioning out of vegetative growth actually needs. The second most common is skipping CaMg entirely in coco, assuming the base products alone cover calcium and magnesium adequately, when coco's binding behavior specifically calls for supplemental CaMg beyond what a soil grower would need. The third is adding all six products to the reservoir in whatever order is convenient rather than following Base A, then B, then everything else, which is the sequence most likely to avoid a cloudy, precipitated mix.
What We'd Tell You at the Counter
If you brought us this exact question at the counter, we'd walk through which stage you're in right now, since that tells us which products you actually need this week, not the whole six-bottle lineup at once. Most growers don't need to buy everything on day one; the schedule builds progressively as the plant moves through its cycle.
We sell the full line and would rather help you buy what this week's feeding actually calls for than sell you all six bottles up front. We don't upsell.
Frequently asked questions
Do I need all six Drip Hydro products from the start?
No. Base A, Base B, and CaMg cover vegetative growth; Flex, Flow, and Ooze enter progressively as flowering advances, so most growers build up the full lineup over the course of a grow rather than buying everything at once.
Why does mixing order matter for a 2-part base?
Concentrated together before dilution, the calcium in Base A and the phosphates in Base B can react and precipitate out of solution. Adding Base A first, letting it dissolve, then adding Base B avoids this.
Should coco growers run more CaMg than soil growers?
Generally yes. Coco naturally binds calcium and magnesium, making less available to the plant than the same feed would deliver in soil, which is why coco-specific feeding advice usually calls for a heavier CaMg dose.
When should I start tapering Base A and B before harvest?
Most growers begin tapering the base nutrients in the final two weeks of flower, alongside a flush, though exact timing depends on your specific flush protocol and strain.
Can I run Flex without Flow and Ooze?
Yes. Flex is the core PK booster for bud development and works as a standalone addition to the base; Flow and Ooze are additional layers for growers who want the fuller schedule, not a required pairing.
Once your feeding schedule is dialed in, silica is a common next addition; our silica supplements guide covers that decision across four brands. Because, as always, we don't upsell.
