BLOOM / FLOWER STAGE

1

Lighting Changes

Provide 12 hours of light and 12 hours of darkness each day to induce flowering. Use a timer to automate the light cycle

2

Nutrient Changes

Use a bloom nutrient formula that is high in phosphorus and potassium and low in nitrogen.

3

Air, Temp PH and CO2

Continue to provide fresh moving air, adequate water, and nutrients, and monitor the soil's pH level.

Lighting Changes

Keep Your Pig Skinners Off the Baby Buds!

01

What You Will Need

​

  • The same grow space, now cleaned up.

  • A reliable timer set to 12 hours on / 12 off.

  • Plant ties or stakes for support.

You’re not changing the whole setup—just the light cycle and how gently you handle those buds.

03

Lighting Changes

Lights go to 12 Hours on, and 12 hours off to jumpstart Flowering.

 

Set your timer to 12 hours on, followed by 12 hours of complete darkness.

  • Lights on and off at the exact times daily.

  • Keep the dark period truly dark—no opening the tent, no room lights on, no glowing power strips shining on the plants.​

 

This consistent light/dark cycle tells your plants, “It’s time to make flowers.”

  • Height Changes as Plants Grow​

  • Spectrum needs to change

​

​

02

2x Size from Grow to Flower

​

When you flip to 12/12, plants usually stretch—some double in height during the first 2–3 weeks.​

  • Leave enough space between the top of the plant and the light before you flip.

  • If they start to get too close, gently bend and tie down tall tops instead of snapping or hacking them off.

Plan for that growth spurt so you’re not wrestling a jungle under the light.

04

Propping Them Up

In the Grow Stage, we were tying down branches and spread them out to allow light in and increase the spread for future big buds.

Now as the buds grow heavy the emphasis will be on keeping them fat and gooey bud-laden branches propped up. 

As flowers stack, branches get heavy.

  • Use bamboo stakes, yo‑yo hangers, or a trellis net to keep colas upright.

  • Tie branches loosely; you want support, not strangling.

The less you manhandle the buds, the more resin stays on the plant instead of on your fingers.

Nutrient Changes

Your Plants are Gonna Love You.

01

What You Will Need

  • Your same base soil and pots.

  • An organic “bloom” formula, lower in N, higher in P and K.

  • pH test tool (even with organics, it helps).

 

Flowering is a menu change, not a full kitchen remodel.

02

Use Bloom Formula

 

As you enter bloom, plants want less nitrogen and more phosphorus and potassium for bud building.​

  • Switch from “grow” to “bloom” nutrients at or just before the flip to 12/12.

  • Start at half the bottle’s recommended dose and only increase if plants stay hungry (pale, slow).​

  • ​

Overfeeding doesn’t make bigger buds; it makes burned tips and lockouts.

03

Over/Under Watering

 

Bloom doesn’t change the basics: roots still need air.

  • Overwatering (pots always heavy, leaves droopy and swollen) can lead to root issues and slow flower growth.​

  • Underwatering (pots bone dry, leaves drooping and crisp) stresses plants and can cause foxtailing and reduced yield.

 

Keep your same “finger test” rhythm, but notice that big blooming plants can drink more than veg plants.

04

Over/Under Feeding

​

  • Signs of overfeeding: dark, clawed leaves, burnt tips, and crusty salt buildup on the soil surface.​

  • Signs of underfeeding: pale yellowing between veins, slow growth, skinny buds.

 

If you see burn, back off on nutrients and water with plain, pH‑adjusted water for a few irrigations.

 

If you see an apparent deficiency, gently bump the dose or add a light top‑dress.

Air, Temp PH and CO2

The Secret Sauce

01

What You Will Need

​

  • Exhaust fan and intake or passive vents.

  • At least one oscillating fan inside the space.

  • Thermometer/hygrometer combo (cheap is fine).

  • pH test kit for water.

 

This is your plant’s life support system.

03

pH Levels

​

Even with organic nutrients, wildly off pH can slow everything down.

  • For soil grows, keep water roughly in the 6.0–7.0 range.​

  • If you see multiple deficiencies at once, check pH before you dump more food in.

Stable pH means the plant can actually use what’s already in the soil.

02

Airflow and Temp

 

In bloom, dense buds hate stale, humid air.

  • Aim for temps around 68–78°F and humidity near 40–50%.​

  • Run your exhaust enough that the room doesn’t feel stuffy, and aim the internal fan so leaves gently dance, not flap violently.

 

Good airflow helps avoid mold and keeps COâ‚‚ moving around the leaves.

04

COâ‚‚

​

Most home grows do fine with normal room air; plants use the CO₂ people and pets exhale.​

  • Fancy tanks and controllers only make sense once you nail light, environment, and feeding—and usually in sealed, higher‑light setups.

For now: fresh air in, stale air out, and your plants are happy.
