Light burn2 fairly new leaves at top (opposite ends) seem to show signs of light burn (yellow tips). They recently turned a bit more green but the tips are still quite yellow. Light = 13 inches away. PAR 370 at center, 350 on sides. DLI=~ 22.5. CO2 bag in tent (at about 620). Thoughts?

How big of an issue is light? HELPHow do you know whether to raise or lower your lights? My LED is pulling about 250watts from the wall... Box said keep light 30" away during veg... But I'm not so sure about that. Thoughts? How will I know if it needs more/less light?Setup. Lighting

Which LED light for 2'x3.5'x5.5' perpetual DWC autoAfter this run I think I'm going to grow 2 DWC autos at a time and harvest monthly. I'm looking at a 6x 3k COB, a 58 SMLEDs 2 CREE COBs (3k and 5k), or a 112 SMLED and 4 CREE COB (3k).

Does anyone have experience with colas that have been severely light deprived, yet still have trichs?My ghost nug grew up on the side of the tent blocked from light. She has trichs, looks super light yellow (see pics). My question is, wouldn't this be desirable? Less chlorophyll to wait on before smoking? Has anyone tried to maybe light deprive parts of their colas?

Lighting questionI am running the Viparspectra 450w LED as my light for 4 autos in a 2x4 space. I am worried this isn’t enough, especially because of its lower levels of red. Should I upgrade to something stronger like a Mars hydro 600 or 1000 before flowering start?Or if not Mars something else?Week 4

Maximum / Optimal Lux or FC for LEDs and checking readingsI have a Viaspectra P2500 which is a bit big for my tent but I figured I could dim it and have when I upgrade my tent.
I think I am burning my plants though so I am wondering what the maximum and optimal Lux/FC is for LEDs. I have the Light Meter LM-3200 app with diffuser. Ty

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!Setup. Lighting

And if it's not difficult, tell me how I should control the light at all stages of growth from growth to the end of flowering!? at what distance from the plants should the light be? and what power adjustments on the driver should I make?

Light ScienceHas anyone watched some Youtube videos by Dr Bruce Bugbee from Apogee Instruments? I find his lectures on lighting to be the most straight forward explanations I have heard yet. I found his vid called "The New 400-750 nm ePAR Range Explained with Dr. Bruce Bugbee" to be eye opening on lighting colours. I have changed my LED's based on a few of his vids. He explains what plants really want and those Burple lights just don't cut it.
For those that don't know he is a professor at the University of Utah that legally studies cannabis growth.
He takes the science of weed grow to a whole new level.Setup. Lighting

Change lights off time?I'm having trouble with temperature control. My nights get too cold. My current lights off time is 12am-6am. Is it possible to change it? I really want my lights off to be from 9am-3pm. I think that would help me a lot. How do I change it? Let my lights run for 27 hours?Setup. Lighting

Longer Light Cycle - Mid BloomIs changing the light cycle of an autoflower from 18/6 to 20/4 in mid flower too stressful? Doing so would bump my DLI enough to keep my existing light through harvest. She sleeps like clockwork but less so now in mid flower. Will she adjust in a couple days to a longer day?Week 8
