Is it better to have one light unit that covers the full area of the tent or use multiple smaller ones? Im using 2 small leds. Is it better to have the ability to dim the lights or just have one power of intensity?

Discoloration and patches on the top sugar leaves
Leaves circled have gone lime green to yellow with the dark and light spots shown in the image. Is it light burn, wind burn or something more sinister?!

Light Decrease, yay or nay? (I'm in no rush)
SHOULD I DECREASE LIGHT TO 10 HRS TO SIGNAL TO THE BUDS ITS SNIPPIN' TIME? I'm in no rush, only that the light setup is not ideal for younguns! Don't wanna bully them til they're frail and weak... and not dank.

How many plants in a 70x70x160cm tent with 100W?
Hello, I have a grow tent kit 2x2 with a 100W 301H EVO Spider Farmer light. I have put there three 11L pots. But now I realize the size/light of my tent might not be enough. Could I manage by adding an additional 60W lamp you reckon or is it best to discard at least 1 plant? Thx

ViparSpectra P600 or P1000?
I'm just starting with a small setup (40x40x100cm tent), only one small plant at the time, but want to be able to grow proper quality in long-term. I suppose the biggest difference between the two lights is the 930 vs 1006 umol/m2/s? Any advise appreciated!

Started the plants off with 60 watts. Increased to 100 watts today with a 20/5 schedule. Could I increase to the full 150 watts already or should I give them a few days with 100? Thanks in advance for any advice. It’s my first indoor grow with this setup and I’m still learning :)

I need help choosing a better light for my single plant microgrow!
H50cm W37.5cm L57cm Now using 1 household 13w Phillips LED 2700K for flower, a 120w CFL for veg and I use a cheap 20w dual Spectrum LED that I'm sure does almost nothing. See pics for convo with led sales guy. Is the height really that much of an issue with the light intensity?

Can anyone recommend how high and what percentage to run my light. The leaves have not been strongly perked up in a few days and I wonder if it's that the intensity of light is too high. I've been at 80% at around 14 inches. vipraspectra p600. Critical purple auto.

If I move 3wk old S.Diesel & Critical from 18hrs💡indoors to outdoors where they'll get +/-11hrs direct🌞. Is there still a risk of them going into flower even though they're still babies? I really don't want this to happen. They'll be in the woods so no chance to add extra light
