Full Grow Tent

1. I need to do more research on my light, it's so bright and the tent is so full that a few of my plants got some intense light burn. I'm putting them on a 18/6 light schedule until I can figure out a way to dim the light. 2. I'm currently only giving them 5.5 PH water and no nutrients. I'm seeing some minor nutrient burn on the tips of some, but not much, but I also know I've been a little heavy with the nutrients. I use a big gallon water spray to water them, but I don't think I've gotten my measurements 100% correct. For my next grow, I'm using only dry nutrients, no more liquid. 3. I'm watering them 2x a day, night and day because they are drying so quickly. I usually check them when I wake up and then do care for the day. But I have a habit of checking them anytime I've been gone 6+ hours which has lead me to watering 2x a day. It's not a lot of water for them, but I think it helps. 4. I'm definitely doing 3 plants next go around. The tent is packed and I think it's even hard for them in there so I've learned a lesson with that one. And as you can see one is taller than the light lol. We call her a Stallion.
