Is closer to the light much better?
Is the light closer better? I have a VIPARSPECTRA 1000W LED Grow Light (10W LED ,x100) and it says during veg 18-26 and flowering distance at 18-24”. Looking at other growers using LED they are closer. Should I try to keep it closer a little at a time? Is there benefit?

Light burn or nutrient burn?
Hey guys. The tips of my leaves are starting to turn yellow and I’m wondering if this is a nutrient burn or light burn? I lowered my ppm feeding to about 250 a few days ago and am growing in ocean forest fox farm soil. And the light is an optic 2 running just the cobs at 24”.

Hans panel 180 use veg mode or not
I've got a hans panel, it's got veg setting and flower. i had it all day on veg mode, seedling was stretching so i placed maybe 30cm from the lamp, but now leaves turned bit yellow. Would it be better to put it on flower mode and place the seedling further away?

Affordable but good growlight for small space
I'm looking for a cheap light to grow one plant, the current one (90w) have just doesn't have enough juice so I'd like to upgrade. I know mars has some good and affordable lights. Any other brands or not so famous brands in Europe that are cheap but good? Tips are welcome!

light bleaching
Why are my leaf tips getting bleached still? I have the light 18 inches from the canopy which is what is recommended for veg, and that's only around 400umol/m2s but the leaf tips keep burning. Temps are low if anything, consistently between 65 and 75 farenheight.

Light power
Is a 100-watt lamp sufficient? I don't consume much, so I opted for a modest light, anticipating lower yields. Can the quality match that of weed grown under a stronger light(600watt), despite producing fewer grams overall?

2 plants, 2 Mars Hydro TSW 2000’s, need help with pot size/tent size configuration
My plan is to flower these 2 girls in a SCROG under 2 Mars Hydro TSW 2000s (2x300W actual). I’m debating whether to flower them in 5 gallon plastic pots in a 2x4, 10 gallon pots in a 2x4, or 10 gallon pots in a 4x4. Does more area = more yield, or am I thinking about this wrong?

LED light recommendation
I am going to need a new LED light to hang from the ceiling. I am looking for a light that has the red/blue spectrum. A dimmer switch would be awesome- the ones I read about that include-seedling, veg and flowering settings sound amazing. Any recommendations out there? Thanks in

LED distance in grow 80x80x160
I placed the LED at a distance of 45-50cm from the seeds and consequently it was about 65-70cm from the larger plant. I have 4 plants Is it ok like this? I don't have a luxmeter and I use the phototone app to get an idea of the PPFD in each plant. LED QB 120w, LM301H

Posible quemadura?
Cada vez que entro en floración me pasa esto y no encuentro solución. Uso una tienda de 1,20 x 1,20 y tengo un led de 730w empiezo a pensar que la luz es demasiado potente y las plantas sufren de calor. Hubo dos dias en los que llegó a 32 grados actualmente estoy en 29/30

1 light or 2
I have recently purchased a Mars hydro SP 3000. Great light.. It replaces my Blurple Mars hydro exo 120. I wanted to ask what peoples opinions are about me using both lights for veging. My grow space is not that big. 1.8m x 0.8m and 2.35m high. Will it be too much light and heat?
