Day 7: I removed the small Royal Jack Auto, since it hadn't shown any growth in the past 48 hours, and I'm germinating a new seed for the tent today. The remaining plants look robust and are growing fast. For now they're getting plain water only, and I'll water again mid-week. Next week I'll add a little nitrogen, some micronutrients and a drop of Supervit. The light is 35 cm above the canopy. It's a dimmable Mars Hydro, currently set at around 30–35%, so every plant gets roughly the same amount of light. Below is a conversion Gemini gave me. Lighting data (Day 7) - Lamp: Mars Hydro TS2000 - Height: 35 cm above the plant tops - Dimmer: 30–35% - Foot-candles: 940–1,100 FC - Lux: 10,114–11,836 lux - PPFD: 151–176 μmol/m²/s I'll wait until every plant has its third set of leaves before raising the power to around 40–45%. My usual light schedule for autoflowers: - Days 9–14 (early veg, third leaf set): 40% dimmer, about 200–250 PPFD - Days 15–21 (mid veg, multiple nodes): 50–60% dimmer, about 350–450 PPFD - Days 22–28 (late veg, pre-flower): 70–80% dimmer, about 550–650 PPFD - Flowering (week 5 onward): 100%, about 700–900+ PPFD Day 8: Thick, short stems with no stretching, and the second set of true leaves is fully formed. Day 9: 150 ml of water each, poured in a ring 6–7 cm from the stem. Day 10: The third and fourth sets of leaves are coming in strong. The structure is very compact and the leaves are a healthy, firm green. I gave each plant a single drop of Supervit. I plan to raise the dimmer to about 40% in the next day or two, depending on how the Royal Jack develops. I'll also raise the lamp a little, because the plants are getting taller and I don't want the new seedling to struggle right under it. Day 11: The replacement Royal Jack seed germinated today. The two Atlas are compact, with short internodes and no stretching. The Royal Jack is a little smaller, with narrower, slightly darker leaves, but it looks healthy. Day 12: I raised the lamp a few centimetres and set the dimmer to 40%. The replacement Royal Jack went into its 11 L pot, watered around the plug with Easy Root bacteria, under a cut-bottle dome to keep the humidity up. The larger plants are starting to push side branches. Day 13: No stress from the jump to 40%. The Atlas leaves are wide and well spread, with new side shoots at the nodes. The Royal Jack has put out a new set of leaves and is growing day by day, just more slowly than the Atlas. The replacement's cotyledons are open and healthy. Day 14: Today the three larger plants (2x Atlas F1 Auto, 1x Royal Jack Auto) got their first feed, RQS Easy Grow plus Easy Plus, at 30% of the recommended dose. The Easy Grow tablet is 3 g for 10 L of water, so I used 0.06 g in 0.7 L: about 260 ml for each Atlas and 160 ml for the Royal Jack, poured around the edge of the canopy rather than at the stem. I'm starting low on purpose: you can always add more nutrients later, but you can't take them out. There's also already 50 g of Easy Boost mixed into the soil. With autoflowers I always use bottled water during veg. The water I drink has a perfect pH of 6.3, but it's low in calcium and magnesium, which is why I've already added some Easy Plus. The last plain watering was on day 9 (150 ml each). All three look healthy and compact, with no stretching. The replacement Royal Jack stays under its dome until its first true leaves appear. The light is at 40%, about 40 cm above the plants. Next step is 50% for days 15–21.
