Mars Hyrdo TS600 - 100w but mistook for 600w
I've recently found out that the led light I have which is a Mars Hydro TS600 is not in fact 600w and is actually 100w. Do I need to compensate in any way? My plants look healthy but short, I don't want to put the light too far away that it's ineffective, how close is too close?

How much light does a seedling need?
Is there a limit to what it can use? Could an LED grow bulb a couple inches away provide enough light? Up to what age? Thank you so so much. My first grow and I really appreciate it! Specifically this one https://www.gelighting.com/led-bulbs/e2624/ge-grow-balanced-spectrum-br30#

Are these LEDs good?
What do you growmies think of these lights? They're LED's, I have 2 of these going and a few other lights. These though, I don't understand much about electrical info. My green seems to like them ok but are they good? I know to the experts out there, this probably seems dumb, but

Turning lights off before harvesting
I've seen some growers who turn the lights off a couple of days before harvest, and I don't know why. Are there any benefits to doing this? or concerns?

Slight leaf tip "burn"
What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000

Light distance and power with a 205W Sanlight LED
Sanlight told me I should use it dimmed at 80% and 45cm when in flowering. I was aiming to reach lower buds so I put it at 100% and 50cm from the upper buds. The tips of the leaves are slightly burned but no bud bleaching yet like my last run (at 100% 45cm). What's best ? Thx !

How to switch to flowering
It's been about 5 weeks from germination. I think we're ready to switch to flowering. I'm just not certain on how to go about it. Do I gradually reduce 18/6 of the veg light down to 12/12 (over a week?) then pop in the flower bulb? Or do I just make a hard switch?

Currently running my KingLED 2000 with both Bloom and Veg switches on. Is this the correct time to go just with the Bloom lighting? There's no harm in running both throughout; correct? Except to the power bill of course. Any thoughts?

light on humidifier :(
okay I think I might have fucked up (lol). I bought a new humidifier. And I didn’t realize it has a light in it. And i run it in the ten over the whole night. It’s not powerful at all but it’s also not just a little led. Do u recon my plant will be okay. I covered it now.
