plants are looking healthy bro...
I'd pull them out of the room during the dark period when you test your 1000w setup to make sure the room stays cool with it on... that way it won't harm them if it does get hot...
I'll post a picture for you of some of my plants that are just finishing week 5 of flowering (no veg time) for insperation...
Some OG
Some Fruity Strain (not sure what it is)
