Lights? Height above plants?
HLG has a calculator for light x draw = and such for mathematical PPFD
Then others for computing.
UT383BT helped me set height and decide to discard China Cheapies for HLG
Twice the light and half the power draw. Lower Tent temps is a benefit I didn’t plan on.

No. HLG website information on your light is good.
My 350R @ 15inches and power position #5 is 70,000 at canopy.
Less, for lower areas.
Leaf temp still -5 from ambient (not overheating), as measured with laser temp gun.
Your light is better and try to avoid light burn.
How high are you lights?
Ambient temp & Leaf temp?
Manufactures’ recommended flower height?
HLG shows 18 inches for Scorp D
Optimize your grow.
Good growing to you
Considering HLG UVA?

They are about 18 - 19 inches from the highest cola. It’s about 80 degrees with lights on and around 70 when lights are off. Hoping they don’t stretch too much more I don’t got anymore room to higher my light lol. I honestly don’t know what the HLG UVA is. Also I appreciate all your feedback thank you

Leaf temp?
Leaf Temp Minus Ambient needs to be negative, else plant is working too hard.
I cant get to 80 with lights on, w/o cooking.
I am doing 75degrees with about 450 watts from HLG’s @60% (350R/260D-K+UVA-30),
16 inches above highest canopy and everybody else, lower.
in the 4x4 and leaf temp is usually -3 to -5 from ambient.
Good growing to you.

Today was week 4 flower. Got some defoliation done today. Got a lot more work to do. Definitely not gonna get every sucker buds.

Monday will be 6 weeks into flowering. Did all my major defoliation already. I know I probably didn’t get everything, but it is what it is. The only thing I plan on doing is cutting some fan leaves here and there to help some bud sites that are blocked. Other than that everything is looking pretty good in my opinion. Definitely see some yellowing happening, but I feel like that’s natural in this stage.

Doesn’t HLG have clips for attaching to HLG lights?
I hang mine under the HLG’s in the middle, perpendicular, where no LEDs exist.
Daisy chained to 260, for control.
