Sejanus21 # CBD Winter Grow - Week 2 Update (Dec 13, 2025) ## Current Status **Day 19 since germination | Day 13 since transplant into final containers** - **CBD Delight**: 7cm height, excellent lateral growth - **CBD Relax**: 5cm height, compact structure Both plants showing good bushing and node development, though some minor leaf issues have appeared. ## Growing Conditions **Environment:** - Temperature: 21°C average - Humidity: 63% RH - Light: SanLight EVO 3-80 at 40cm distance, 30% intensity **Setup:** - Container: Lechuza LS 35 with recycled Pon substrate - Watering: Every 3 days with nutrient solution ## Nutrient Strategy **Current formula (per liter):** - 0.25g Calcinit - 0.3g Hakaphos Green - 0.3ml Fulvital Plus - 1ml phosphoric acid 8.5% (pH adjustment) - EC: 1.4 mS/cm - pH: 5.8-6.0 ## Observations & Adjustments **Issue identified:** Minor leaf discoloration and slight edge curling on both plants. Analysis suggests magnesium deficiency despite adequate EC levels. **Root cause:** Combination of LED lighting (higher Mg demand), recycled Pon substrate (depleted reserves), and Hakaphos Green not providing sufficient Mg for this specific system. **Fungus gnats:** Discovered that the recycled Pon substrate contained some fungus gnat larvae from previous grows. However, given Pon's purely mineral composition with zero organic matter, this shouldn't develop into a persistent problem - the larvae have nothing to feed on. **Solution implemented today:** Adding Epsom salt (MgSO₄) to nutrient mix: - New formula includes 0.1-0.15g Epsom salt per liter - Expected EC: ~1.5-1.6 mS/cm - Should see improvement in new growth within 3-5 days ## Key Learnings Interesting discovery: outdoor grows in soil didn't require supplemental magnesium, but the indoor LED + Pon system does. This appears system-specific rather than strain-specific, likely due to: - Higher photosynthesis rates under full-spectrum LEDs - Depleted mineral reserves in recycled substrate - Consistent environment driving higher nutrient uptake ## Next Steps - Monitor new leaf development for health improvement - Continue 3-day watering schedule with adjusted formula - Old leaf damage will remain, focus is on new growth quality - If improvement confirmed, Epsom salt becomes standard addition Overall quite satisfied with the lateral growth pattern. These Paradise Seeds genetics continue to show their reliability even when minor issues arise. --- *Growing in NRW basement setup with SanLight EVO 3-80*

Sejanus21 # CBD Winter Grow - Week 3 Update (Day 12-19) **Date Range:** December 13-20, 2025 **Strains:** CBD Delight & CBD Relax (Paradise Seeds) **System:** Lechuza LS 35 with recycled Pon substrate **Lighting:** SanLight EVO 3-80 ## Current Status (Day 19) Both plants are developing well after successfully managing an EC crisis: - **CBD Delight:** 10cm height, compact growth - **CBD Relax:** 8cm height, showing characteristic leaf morphology ## Key Events This Week **EC Crisis Resolution:** After again discovering extremely high runoff EC values (2800-3200+) on Day 12, I implemented a systematic rainwater flushing protocol. The recycled Pon substrate was releasing stored nutrients from the previous grow cycle through zeolite ion exchange. **Recovery Protocol:** - Multiple rainwater flushes to reduce substrate EC - Current runoff stabilized at EC 2000 (Delight) and EC 2400 (Relax) - Resumed feeding today with EC 1000 input (Compo Complete + rainwater, pH 5.8) - 3-day watering intervals with approximately 1.5L per container ## Observations **Positive Signs:** - New growth showing healthy green color - Plants expanding laterally with good internode development - Strong stem development on both plants - Active recovery from nutrient stress **Legacy Issues:** - Older leaves show discoloration from the EC crisis - these won't recover but document the stress period - New foliage is completely healthy, confirming successful crisis management ## Next Steps **Topping scheduled for Day 26** (December 29) - waiting one more week to ensure: - 5-6 developed nodes for optimal branching - Complete recovery from stress period - Following Paradise Seeds' 4-week recommendation The EC crisis demonstrates the importance of monitoring runoff values, especially with recycled substrate. Both plants are now on track for healthy development. --- *Setup: Indoor basement grow, NRW, Germany | SanLight EVO 3-80 | Lechuza LS 35 + Pon*

Sejanus21 # CBD Winter Grow 2025-26 | Week 4 Update **Grower:** Sejanus21 | **Location:** NRW, Germany **Period:** December 21-27, 2025 (Days 26-33) --- ## QUICK STATS **Strains:** CBD Delight & CBD Relax (Paradise Seeds) **System:** 2x Lechuza LS 35 (13L) with recycled Pon substrate **Lighting:** SanLight EVO 3-80 @ 40%, 18/6 cycle **Environment:** Basement, 20.5°C avg, 56% RH --- ## WEEK SUMMARY Week 4 brought strong vegetative growth and successful topping execution. Both plants showed complete recovery from early EC stress and developed strong structure for training. **Week Highlights:** - Strong growth: +7-8cm vertical in 7 days - Roots reached reservoir (Day 33 confirmed) - Successful topping above 4th node - EC management optimized for recycled Pon - Clear phenotype differences emerging **Growth Metrics:** - CBD Delight: 10cm → 17cm → 13cm after topping - CBD Relax: 8cm → 16cm → 12cm after topping --- ## PHENOTYPE OBSERVATIONS **CBD Delight - Sativa-Dominant:** - Narrower, serrated leaves - Longer internodes - Stretchy growth pattern - Will likely dominate final height **CBD Relax - Indica-Dominant:** - Broader, rounder leaves - Tighter node spacing - Bushier structure - Better EC stress tolerance --- ## NUTRIENT MANAGEMENT **Week 4 Feeding:** - Compo Complete @ EC 1500, pH 5.8 (rainwater base) - Irrigation: 1.5L → 1.25L as topping approached - Runoff EC climbing to ~2900 (zeolite release from recycled Pon) **Topping Day Flush (Day 33):** - Rainwater flush before topping - Goal: Reduce EC below 2000 for stress-free recovery **New System Starting Week 5:** - Haifa Polyfeed 18-18-18 @ 0.7g/L - Yara Calcinit @ 0.5g/L - Fulvital Plus @ 0.5-0.8ml/L - Target: EC 1800, pH 5.8-6.2 Professional agricultural-grade system provides complete nutrition with EDTA-chelated trace elements at significantly lower cost than cannabis-specific brands. --- ## TOPPING EXECUTION (Day 33) **Strategy:** Cut above 4th node (not 3rd) - Creates 4 equal main colas from nodes 3 & 4 - Better canopy balance for limited vertical space **Pre-topping:** 17cm (Delight), 16cm (Relax) **Post-topping:** 13cm (Delight), 12cm (Relax) Clean cuts with sterilized scissors, rainwater flush immediately before. Photo documentation completed. **Expected Recovery:** 5-7 days pause, then dual cola development resumes aggressive growth. --- ## ROOT DEVELOPMENT **Milestone:** First roots visible in reservoir on Day 33 (both plants). Healthy white roots confirm successful establishment in recycled Pon despite initial EC challenges. Validates approach and enables increased feeding capacity going forward. --- ## RECYCLED PON INSIGHTS Key learning this week: Zeolite in recycled Pon releases stored nutrients (Ca²⁺, Mg²⁺, K⁺) from previous grow, causing elevated runoff EC (2400-2900 range). **Management:** Monitor runoff EC regularly, flush with rainwater when 2500 to maintain 1500-2200 target range. **Benefits confirmed:** Excellent root development, superior aeration, cost savings, proven track record from outdoor CBD Delight (197g harvest). --- ## WEEK 5 PRIORITIES **Recovery Phase Focus:** - Monitor topping wound healing - Watch for dual cola emergence (Day 38-40) - Implement Haifa Polyfeed system - Maintain runoff EC
