Water & Fertilizer Mixer

🚿

Every 4th Watering — NO Fertilizer!

Flush to prevent salt buildup. Same canister, but no additives.

⏱️

Measure pH after 2-3 minutes

Wait after adding fertilizers — micronutrients don't dissolve instantly, pH may drop by 0.2-0.4.

📊

PPM ±10-15 is normal

78/120/152 are guides, not dogmas. If the plant is healthy and roots are white, everything is fine.

📋

Order: CalMag → PPM → Fertilizer → pH

🔬 Step-by-Step Guide: Preparing Water

Start with pure RO water. PPM should be near zero (0-10).

Bring PPM to the target group value: A≈80, B≈120, C≈150.

💡 This base is the same for flushing and feeding!

PPM will rise by 50-150 — this is normal! Fertilizer = salts = higher PPM. No need to adjust.

Micronutrients don't dissolve instantly. pH may drop by 0.2-0.4 after full dissolution.

Target pH: 5.8-6.5 (depending on the group). Adjust pH LAST — after all additives.

Water is ready for use. PPM after fertilizer: 130-300 is normal.

Target PPM (80/120/150) is the CalMag base. Fertilizer is added ON TOP:

+ CalMag

80-150

← target

+ Fert

+50-150

Total

130-300

✓ OK

Controlled release fertilizer — slowly releases over 3-6 months

⚠️ DO NOT use for wick watering!

Granules wash out and burn roots. Top watering only!
