That’s sound like a pretty darn good range for them with out the dome. If that’s the case I wouldn’t cover them as those numbers look good to me. As long as they are fairly consistent in a 24 hour period. Some swing is fine just not more than 10-15%
If more than that dome them up when needed.
So let me make sure I understand what you have going on. Looks like you have 4 plants pretty far along into veg. Correct.
And you have these seedlings in solo cups.
The tent at 5x5 will be fine for the 4 plants your getting ready for flower. All the new seedlings what’s your plan? Do you have another space for them?
As far as up potting them it depends on what available room you have. If you have the room I would put into the final size pots once you have a good root structure in those solo cups. Will be awhile as they are just starting to root underneath and grow up top. If you need to manage the available space…say a closet set up for seedlings and smaller veg plants in 1-2 gallon containers (can be bigger just depends on how many and availability of space you have)
5 gallon is in my opinion a minimum with Photo plants vegging for 8+ weeks if your running Autos 3 gallons will work. If you plan on vegging shorter than 8 weeks say 6 you may …may…be ok with smaller than 5 gallon … bigger pot more roots more plant.
Lighting is pretty much at the top of the ladder as it’s the real food for the plants so when you are able buy some LED high efficiency (efficacy) lol drbn lights for great growth and thick dense buds.
Take a look at this forum do a search for lighting and read through some things.
I upgraded to HLG lights and Photo Boost lights and am amazed. When adjusted correctly at the proper height above the canopy and set at the proper intensity they will positively impact your grows with bigger thicker denser buds…
Your feed the soil the soil critters feed the roots (below ground) all the while the lights (sun) feeds the plants above ground.
Here is an option for the 5x5

And another option X 2 fixtures …maybe…having a hard time coming up with 2 covering the 5x5. But maybe …

Again I’m not an expert on any of this just my experience and learning curve but @dbrn32 may better assist you on lighting for sure and the light you have without knowing the brand and model I couldn’t say for sure but the draw from the wall may be much less than 1000W and may be fine for seedling and vegetative stage but may not have the coverage and intensity needed to flower your space at 5x5 and give you and your time the best results that can otherwise be obtained.
Ok I’m done rambling lol
Hope this helped and let us know if you have any more questions …
Just paying it forward
If the lights were too close with the veg and bloom both on than yes it may have messed them up but they can both be on at the same time and not kill them nor negatively impact them much it’s just veg is more blue and bloom more towards the red spectrum.
Again what light fixture Brand / Model are you using now?
Sorry for the long post but hey I’m medicated lol
Hope this helps and HAGD
