4x8 to much Led

Was up , this is currently my second grow first time with leds , I currently have five 450w leds in a 4x8 tent. I have four 450w viperspectra reflector series and 1 450w viperspectra 450par I'm using two of the reflector series and the 450 par led at the moment with bloom and veg on ( so I'm using 3 out of the 5 ) , under them I have nine seedling. Four of them are auto flowers and 5 are seedlings. All four of my autoflower seedlings are in cyco coco getting feed ph perfect sensi 1ml per 500 ml of water. My questions are

1) is three lights on okay for the moment? (should I switch them to just veg

2) should I have all 5 on ( the 3 are basicly all together covering about 4x4 feet the rest if my tent is pretty dim I don't know weather to space everything apart or keep as is )

The picture of the led is a few days old I have them lined up now in a line with the 450 par in the middle now.. any ideas or help to maximize my grow really just worried about my autoflowers right now since my lights will stay on 20/4 for about two months

How old are the seedlings and what are they in container wise. If they are in small containers and you'll be transplanting them later on I would just start with 1-2 lights and wait for them to start outgrowing it before adding another. If they can all fit under 1 light start there. No sense wasting electricity lighting up an empty tent.

I would bring one light down lower over the seedlings and turn off the rest until they outgrow the one light. Add light as plants spread out.
Those lights look like 150w actual watts. I would turn on all spectrum all the time. Plants need all the spectrum all the time. The only difference between flower and veg is light cycle. Same sunlight most of the year.

You should absolutely reduce your light consumption down to one unit for the sanity of those seedlings. One of those lights will provide more than enough light for the next two weeks.

As the plants grow up add additional lighting commensurate to the stage of growth they're in.

1st why would u feed seedlings 2nd you dont need that much light unless you got like 20 seedlings i do about 6 seedlings per 130w then bump em up to 300w for veg and then to 450w for flower all my lights put about 900 par at 20 inches perfect for seedlings

Well one thing you'll need to lower those lights they are not going to have the plants bushy but stretchy. The 3 running for now will work for veg. I have different lights than yours

yea what height are your light at? for seedlings i do 20 inches then 25 after the first 2 weeks then 30 for veg and raise em up for flowering depending on how much the plants stretch.

Thank you all for the help well the lights are about 25-30 inches from the the top of the seedling and well I'm feeding them nutes because the sensi perfect ph I bought says I can and there in cyco coco so there is no other way for them to get nutrients im feeding them 1 ml since the bottle said so I gave it a go I'm running all 3 because I read with auto flowers u want them to jump to a good start but I'll defenitly just use two of them instead of 3

About 25 inches away should I maybe instead of turning off the 450par since its adjustable just turn of the red and leave the blue and white ? Sorry u guys for all the question it's my first day here and I am very Nubish.
