First grow. Growing autos from meph in a 3x3 tent. They are in the w/3 of flower. On 24 hr light.(Accidentally) having a heat wave in my area and can't keeps temps down below 80-85. Will it hurt anything to switch to 18/6 now so I can have lights off when it's hottest part of day

Auto seedlings, lighting question!
Hi! I have a question. I am just about to start my first indoor grow, it’s relatively small, only two plants, both autos. I am using the Telos 6 mesh LED for lighting but I am unclear as to when to switch the power from 25-50%? Is it when the first true leaves appear? Thanks

Viparspectra P2000 height and intensity
For those that have experience with the light I'm using, Viparspectra P2000, how high and what intensity percentage should I have it? Currently I'm at 21" at 75% power. Also, I run it 24/7. I have an app on my phone and it says my DLI is at like 56 which seems way too high.

Will this one be too hot too?
Do you guys think this light will be too hot for my tent? Will it be ok, or bad? Maybe 1500w is too much? Or will the plants grow faster? shorturl.at/grtFL I had to make a short link to fit in question

Yellowing leaves & tips curling down on 14th day. Coco / Autopot / Hesi / Mars Hydro fc-1500
Would gladly use some help with my first grow 🙏 2 main reasons come to mind after googling: 1. I overwatered thinking it's hard to do since I'm using the Air dome. 2. Too intense light. Was checking a lot of growers that actually grow 24/0 and went for it 75% 40cm.

Autoflower light schedule
Soon rolling into veg for my first auto grow. Currently on an 18/6 light schedule using Mars Hyrdo II 700w . Don’t have any problems with temp/humidity inside tent. Once you notice the buds starting to flower do you switch to 12/12 or just keep plugging away with 18/6?

Can I change my autoflowers light cycle withou reducing their yield significantly?
I am having humidity/mold problems and was thinking of changing the cycle so the grow goes off at noon ( currently it goes off at 1am and its winter and gets real cold with 88% humidity). Even if I stress them, it would be better to not have mold than reducing the yield, right?

Hi! I have just changed to 12/12 bloomtime for my girls. I have a wifi-cam installed so I can check in on them when I want. It has night vision so there are a few red dots(led) from the IR. Can they cause trouble nighttime?
