The light is to far away. You have a dimmer so you can put the light closer and run it with less power.

Light timing
My plant has sprouted today, when should I switch my lights to 18 hours and not 24? Also how often should I be watering? Just so the soil around the plant is damp or? Any help appreciated! First ever grow :) blue dream auto 1

Max 180w LED output for 2x4x6 tent with 3 plants. Good enough?
I have a 3-chip 1000W LED with a max output of 180w (Veg 125w, Bloom 55w): I'm growing autos in a 2x4x6 tent. I'd like to grow 3 plants at a time. Do I need another grow light? Will the one I have suffice?

Alright so this morning from 8am to 4pm my power was out. I transplanted last night and soaked the medium pretty well. Will this power outage hurt my girls. Did the temps being 10 degrees lower all day hurt them. How soon will I know if I get root rot or anything of that nature?

When to flip LED's 'bloom' switch on?
When's the best time to flip the 'bloom' switch on my LED with an auto? Should it be at the first sign of pistils or is there a better time to do so? I have already flipped the switch for this plant and kept photo-period the same, looking for info for next grow. Thanks!

Lighting. Increase or stay the same?
Hi, I'm thinking about increasing lighting to 100%... is it too soon? Currently at 60% 20 inches away (manufacturers recommendation.) I'm thinking 100% but staying at 20 inches away.. what's your thoughts? Too soon? (12" - 18" 100% for veg manufacturers guidelines)

Wondering if doing another defoliatation would direct more focus to the main sites? Also I have three other plants that are about 2.5 weeks younger, so I have to keep an 18/6 light schedule. Would I have to switch the flowering plant to 12/12 even though it's an auto?
