I have several question about my setup for the first week:
- is the distance of the light to the plant ok? - is the intensity of 25% correct? - should I remove the seed coat or should I just let Mother Nature do it, eventually it will be blown up..

Is this a sign of too much light?
I’m noticing the leaves grow extremely close to each other, should I be concerned at this stage, should I pull the light higher back? This is day 3 of week 2, I’m feeding it full advanced nutrients line up for veg. And drying out for a day and a half between waterings

Lights affect picture quality
I have just upgraded my lights to HPS from CFL and my phone camera doesn't like the light intensity. The pictures come out with light+dark stripes down them! Does anyone have a solution for this? 📸

Hello, I am using a viparspectra par1200 which has the veg and bloom adjustment knobs on autoflowers. My question is, should I only be using veg during veg and bloom during bloom? Or can I just turn that sucker on full blast the whole time? Thanks

Light cycle messed up do I have leverage for one mistake?
Timer messed up the cycle and stayed on for an extra 12 hours.. So in total she was, for 24 hours in light... Soon as I noticed I manually turned off. Now the question is.. It's messed up and now off when supposed to be on vice versa, does the one mistake matter so much, seeding?

3000 watt power use
This is my first time using such a powerful light in my opinion, 3000 watts seems overkill but that's what i want. The question IS, is it better to have 1-2 plants under the 3000 watt or worth it to manage 4 at a higher distance? Cheers. Don't keep techniques in mind.

18/6 leads to high temps in small tent; change light schedule or stick it out?
Girls are at 18/6 and 3-4 hours before lights out the tent gets up to 90 degrees and humidity can’t compete. Should I wait it out or try 16/8 moving towards 12/12 close to flowering (autoflower). Will lowering light exposure affect yield more than high temps would at 18/6

Grow lamp setting veg or bloom or both?
For my grow lamp settings this early on should I be using the VEG And Bloom spectrums simultaneously? Or just leave in Veg? Since these are Autos I wasn't sure if switching the spectrums was as important as maximizing light.

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?
