Amnezia Haze Auto - Newbie grow (help very welcome)

Nitrous This grow didn’t start from seed—I received the plants as small seedlings, but I wasn’t given any specific details about their age or the type of substrate they were in. At this early stage, I was running a 60W blurple light, which seemed fine for seedlings but was clearly not enough for long-term veg. I also didn’t have a humidifier yet. --Environmental Conditions: -Day Temperature: 22–25°C -Night Temperature: 18–20°C -Light Schedule: 20/4 (though I’m unsure if this was their original cycle before I got them) --Watering: Initially, I used regular tap water with no pH adjustments. First few waterings were not dechlorinated. Later switched to letting water sit for 24h to dechlorinate before use. Waterings were done lightly and only when needed. Tap water EC: ~0.5–0.6 Tap pH: ~7.1–7.2 (non-dechlorinated), ~8.0 (after dechlorination) No pH down was used at this point. No nutrients were added, and runoff was not tested during this time. --Observations: Plants looked healthy and were growing steadily. One plant was significantly shorter than the others (approx. 8cm vs. 12cm for the tallest), but still appeared healthy and vibrant. No visible signs of deficiencies, toxicity, or stress. This was the calm before the storm—everything looked promising at this stage.

Nitrous The Big Changes (and Some First Mistakes) This week marked a turning point in the grow — both in upgrades and in lessons learned. Upgrades: I swapped out the old 60W blurple light for a Spider Farmer SF2000 EVO. I started at 50% intensity and gradually ramped it up to 100% over the course of the week to avoid shocking the plants. The improvement in spectrum and canopy coverage was instantly noticeable. Watering & Feeding: I was watering every ~3 days, around 400ml per plant with pH’d water at 6.1–6.3 using Bio-Down. This is also when I started feeding — and in hindsight, it was too early, especially considering I wasn’t 100% sure what kind of soil they were in. I added: 0.5 ml/L Plagron Terra Grow 0.5 ml/L Biobizz CalMag (this was a mistake — my tap water already contains sufficient Ca/Mg) 0.25 ml/L Plagron Power Roots Bio-Down to reach proper pH Unfortunately, I wasn’t watering to runoff, and had no EC or pH data from the soil. That, combined with the unknown substrate, likely led to a salt buildup that caused issues shortly after. LST: This week, I also performed LST on all three plants for the first time after seeing a tutorial online. I waited until each plant had a developed 3rd node and a visible 4th before starting. The training went smoothly overall — all plants reoriented themselves well — but in hindsight, I probably shouldn’t have trained Savona, since she was already starting to show signs of early droop. It may have added a bit more stress on top of what was brewing beneath the surface. Observations: Diana (left) was taller and more stretchy, with slightly smaller leaves. Savona (middle) was doing well early in the week but began to look slightly droopy toward the end. Géraldine (right) looked compact, bushy, and strong — classic short and stout phenotype. Flush Attempt (End of Week 3): Realizing things weren’t right, I did my first flush to remove excess salts. I used non-pH-adjusted tap water (~pH 7.2) thinking the high pH would help rebalance the acidic soil. These were the readings: Before Flush: Diana: pH 5.6, EC 4.4 (very high!) Savona: pH 5.4, EC 4.0 Géraldine: pH 5.8, EC 2.2 After Flush: Diana: pH 5.8, EC 1.2 Savona: pH 5.7, EC 1.5 (couldn’t get it higher) Géraldine: pH 6.1, EC 0.9 This was the moment I realized the substrate was likely fertilized from the start, and the feeding without runoff had built up far more salts than I expected.

Nitrous Dialed In, But Trouble Deepens This was the week where I felt like I finally had most things under control… but it’s also the week where things started to go seriously wrong. --------------------------- Dialing In Environment: VPD was carefully maintained: 24–25°C daytime 60–65% RH consistently Lighting: Started the week at 100% intensity (Spider Farmer SF2000 EVO, ~45cm canopy distance) Dialed back to 80% on April 20 after noticing worsening signs and realizing it may have been too strong for this stage Watering: Watered only when dry (every ~4 days) This week’s watering (April 20) was about 1.3L per plant, with 15–20% runoff No nutrients added — just pH-adjusted water + ½-dose of Power Roots to help root recovery Pot Size & Drainage: Diana & Géraldine: 4.7L Savona: 5.7L Drainage is excellent, but the root systems are clearly pushing the limits of the pots Roots visible from drainage holes look white and fluffy, which is a positive sign I think — but the limited space may be holding them back --- Symptoms & Decline: What started with Savona now seems to be affecting all three plants in different ways. Savona: Persistent, stiff droop Leaves are rigid but limp, not plump or hydrated-looking Clawing persists, despite the earlier flush Leaves are very dark, especially for this growth stage Diana: Now showing signs similar to Savona Developing brown-bordeaux spots on leaves A few small yellow/brown lesions elsewhere New growth is abnormally dark, possibly stressed New growth started tearing from pressing into lower leaves — now visibly deformed Géraldine: Still the healthiest overall Slight droop present, but less severe Compact growth with tight internodal spacing May be beginning to show early signs of similar issues ---------------------------- Other Notes: Leaves touching the soil raise concern about fungus or mold Incident: my fan fell onto Savona this week — only one leaf was torn (cleanly), but it didn’t help her condition ------------------------------ Latest Watering Stats – April 20 (Clean water + ½ Power Roots — no nutrients) Géraldine EC 0.6 → 0.8 | pH 6.3 → 6.4 Savona EC 0.6 → 0.9 | pH 6.3 → 6.4 Diana EC 0.6 → 1.1 | pH 6.3 → 6.4 Runoff numbers look acceptable, but the physical stress symptoms are ongoing. The clawing, dark foliage, and structural droop haven’t resolved, despite cleaner watering and good environmental control.

Nitrous Recovery Continues & First Gentle Feed After the big flush back in Week 3 (which revealed serious salt buildup), I followed up in Week 4 with a lighter flush, this time with added Power Roots to support recovery. That flush really helped, and by the start of Week 5, Savona and Géraldine were finally starting to perk up. It was genuinely rewarding to see signs of life coming back after all the stress. Géraldine even showed a little yellowing on her lower leaves, but with improved posture and brighter overall growth, it felt like a small victory. Progress! --- April 24 – First Normal Watering with Gentle Feed This week’s watering was the first normal feeding after the recovery period — just a mild nutrient mix with around 15% runoff to ease them back into a balanced rhythm. Feed Mix: Plagron Terra Grow – 0.5 ml/L Plagron Power Roots – 0.5 ml/L Bio-Down to pH ~6.3–6.4 No Cal-Mag this time! (Seriously… heavy tap water + Cal-Mag? What was I thinking? 😅) --- Watering Stats: Géraldine In: 6.4 pH / 0.7 EC Out: 6.5 pH / 0.8 EC Savona In: 6.4 pH / 0.7 EC Out: 6.4 pH / 1.0 EC Diana In: 6.4 pH / 0.7 EC Out: 6.5 pH / 1.1 EC --- I'm feeling cautiously optimistic now. They’re not out of the woods yet, but this week definitely felt like a step in the right direction. If you spot anything strange in the stats or photos, please don’t hesitate to chime in — I truly appreciate the help and support from all of you!
