i’m learning DWC

April 1, Monday: * r-DWC: * ppm: 290-310 * pH: 6.1 * Water temperature: 24°C * Development was observed. * There was red-brown foam in the reservoir. I think it's due to beneficial bacteria from temperature or the filter. It's only in the main bucket, not in the others. The roots are completely white and healthy. * Temperature was lowered, and since the filter was a sponge, it was removed and rinsed with h2o2. * The foam significantly disappeared. * r-DWC: * +1 mL pH- * pH: 6.1 5.4 * + 0.5 mL pH+ 5.6 * +0.5 mL pH+ 5.9 * +4 drops of pH- 5.8 * LIGHT at 25% * All plant leaf damages were cleaned with a sterile razor blade; green parts of the leaves are intact. * r-DWC: * ppm: 310 (stabilized) * pH: 6.0 * +0.25 mL pH- 5.8 April 2, Tuesday: * LIGHT: 50% * r-DWC: * ppm: 290-310 * pH: 6.0 * +0.25 mL pH- 5.8 * Magnesium deficiency observed in lower leaves. Reservoir change and fertilizer increase will be provided, and silica will be added. * Reservoir renewed 50L * Silicate 14 gr * Cal-mag 30 mL * Micro 35 mL * Grow 50 mL * Bloom 18 mL * Fulvic 60 mL * ppm: 540 * pH: constantly rising (silicate) April 3, Wednesday: * r-DWC: * ppm: 560 * pH: 6.1 (constantly rising, despite lowering it below 6 at least 3 times a day) * To reduce ppm and prevent pH rise, I'll add 20 liters of plain nutrient solution. * 20 liters of water (RO): * 20 mL cal-mag * 7 mL micro * 16.5 mL grow * 4 mL bloom * ppm: 500-520 * pH: 6 April 4, Thursday: * The morning temperature reached 25°C, immediate action was taken. * Pump filter was changed. Observed silica and dead roots in the filter. * r-DWC: * ppm: 520 * pH: 5.8 * Total water: 70 liters * Silicate: 14 gr in 10 liters / 2 gr * Cal-mag: 50 mL per liter / 0.7 mL per 1.4 * Micro (soft water): 42 mL per liter / 0.6 mL per 1.2 * Grow: 66.5 mL per liter / 0.95 mL per 1.8 * Bloom: 22 mL per liter / 0.3 mL per 0.6 * Fulvic: 60 mL per liter / 0.85 mL per 1.7 * r-DWC: * ppm: 620 (briefly increased to 530) * pH: 5.9 * LIGHT: %25
