It all depends on the size of the plants! Maybe after the 3rd week of veg is when they really start needing more light!

additional blurple lights
I also got the blurple lights from my friend. To keep the temperature down I haven't installed them yet and not sure if I will. Will they make a difference if I add them next to the current LED? If so should I wait until the flowering stage or anything like that?

Bud too close to the light
Hi. The main bud on one is 10cm from the light. I cant raise the light any higher and have a bit more vertical growth to go. Shall I remove the bud at a lower artery, or leave it and bend it around the light somehow?? Don't want to loose the main bud but will if I have to?!?

Light came on for about 30 seconds about 3 hours into the dark cycle
So Im 3 days into 12/12 and I bumped my timer last night and my light came on suddenly during the dark cycle. I immediately shut it right back off. Was I wrong in shutting it back off right away? Should I be worried about anything?

Burn or ?
leafs feel rough , little tiny greens dots with texture on leaf. I found out after bumping the light up 40% Plants did not like. Looked up manufactures suggested hanging / power. Seems I am over powered. The light is more 4x4 or 3x3 then 2x2 Diary is updated Light or Nutrient?
