White Widow Autos (first-time grower)

Lowered temp and RH a little. Last feeding seemed to have cause nute burn. I will reduce nutes next time, possibly flushing. Increased watering volume for #1/#2 from 0.5L to 0.6L. It looks like #1/#2 may not be ready within 12 weeks as I hoped, as they're still growing vertically and buds haven't developed much yet. Plant 1: Clawing leaves (N excess) finally going away. Buds starting to grow at accelerated rate. DLI/PPFD readings much lower compared to #2, but there's light burn it if I move the light closer Plant 2: Was doing great until I fed her yesterday. Within hours, a few leaves turned yellow, got brown spots, and started taco-ing. Luckily, it didn't worsen today. Trellis continues to be very helpful, as there are a lot of colas Plant 3: Flowering increased, and I'm more hopeful that she will yield. Raised 4" to get closer to light, and she responded well. DLI went from 30 to 36, and PPFD went from 450 to 560 Plant 4: Growth has slowed. I thought she would be a lot taller by now since she's 2 weeks younger than the others
