L.A. Amnesia - Indoor - Rookie (1 chamber)

Hi@ALL, it's the end of the second flowering week, unfortunately, I’m dealing with fungus gnats. As a countermeasure, I’ve used nematodes. The challenge is that during the flowering phase, I prefer to let the soil dry out completely before watering. However, nematodes require consistently moist conditions to survive. Additionally, I’ve read that nematodes can take three to four weeks to eliminate all the eggs – quite a long time. I might also try neem oil. Also, I’ve noticed that the tips of 20%-25% of the leaves have turned brown and become crispy. This occurs both at the top and bottom of the plant. I suspect I’ve provided too much light. My biggest challenge currently is finding the right light intensity. I’m using an AC Infinity Ionframe EVO3 with 280W. According to the instructions, I should operate it at 100% intensity during the flowering phase when it’s 30 centimeters away. However, that feels like a full-blown laser show for the plant. (supposedly around 1600 PPFD). Now I’ve positioned it at 45 centimeters and 70% intensity. According to the Photone App, the upper part of the plant receives approximately 900-1000 PPFD. Unfortunately, I can’t fully trust my smartphone an the app… well, that’s what happens when you turn everything into science 😅 And one more thing caught my attention: the smell. It’s not there. I can hardly smell anything. My GG#4 is three weeks old and fills the entire room with its strong odor, but the L.A. Amnesia simply doesn’t smell like anything. Somehow, that worries me a little 😩 Overall, the plant seems "healthy" and does its thing, but I’m unsure whether to prune the lower branches. Although they receive light, they’re about 10-15 centimeters below the upper ones 😓 Wish you a nice day. 👋😀👍 GrowHard.GoPro. 💪
