Blue Dream - My Second Grow Ever

The weather here in Colorado has been back and forth, per usual. It has been in the 80's and then snowed last night (4/19) so the humidity/temps have been variable inside the tent. On 4/11, I turned my third light off because it was getting into the low 80's inside the tent as it was very hot outside that week. I have Blumat water meters and water each pot when it gets to about 70-80 mbar. I find that about 1/3 of a gallon tends to be the sweet spot when it comes to watering. On 4/14, I raised my lights up to 33" and turned the LEDs down to 80% as I noticed an upward curling on a few of the leaves. On 4/18, turned the LEDs back up to 100%. The two big plants are getting about 310-315 PPFD and the little one is getting about 280. On 4/19 around 5:30 pm I began LST on the two larger plants. This is the first time I have done LST so I am excited to see how this impacts plant growth. The little plant is starting to grow quickly now.
