Lowering light
Should I lower my lights and decrease the intensity to get better penetration or keep them the same height and increase intensity? (These are auto flowers about 50 days old getting towards the end of flower)

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?

I purchased two Vipar Spectra 300 LED Lights. I am only using one right now because i was concerned two would be too much for the seedling phase. Should I keep just the one light or Put up Both ? When would be a good point in the plants life cycle to put up the extra lights ?

Seedlings
Woke up this morning and she’s grown a bit from yesterday. 4cm tall now. HLG 135 was dimmed (to a level that was comfortable to look at, I have no way of measuring output right now) and is 26” away. I know it’s early but I have no experience!

Short period grow
Hey fellow growers. So I have an odd question, Is it actually possible to start grow with 12/12 straight away? And how will it affect my plants? Let's say I have 3 autos and one photo. Will I have anything worth the time if I start straight with 12/12 light schedule? Thanks you

Light height and intensity
Hello all. Recently I upgraded my lights to 2 mars tsw 2000. I've noticed my plants are growing slowly compared to everyone else's. I have it set at 24 inches 25%. However a mars hydro admin posted 12 inches 75% during veg? Isn't that like 1500 ppfd? I'm so confused.

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”.

Plantulas deben estar bajo luz?
I have a 240 watt 3500k quantum board LED. Does anyone know how long it's recommended to give them light with it? It has a dimmer, but I don't know if they need light in the seedling stage. This is my first time starting a grow with LED. Before, I would just put them in the sun for a few hours and that was it..
