White Widow Autos (first-time grower)

Better than the past 2 weeks! I realized I was underwatering and possibly underfeeding. Increased watering to 0.5L every 2 days. I previously was watering every 3 days without measuring the amount. I keep on raising the lights because of 1&2's growth, so I put some risers under 3&4 to make up for it. I also covered the blue LED lights since all are now in flower. Plant 1: Started growing vertically again, although it still has much less branches/colas than Plant 2. Also reacts better to waterings better than 2 (more praying, not droopy). Leaves tips are also spikier than 2's and have buds in different places compared to 2 Plant 2: Looking great! Using the trellis a lot and it's growing both vertically and horizontally Plants 3&4: Both showed pistils and received flowering nutes for the first time
