1 week from flower- any tips?

[1st timer]

Nice job, the plants look good. :thumbsup: Certainly on the large side for a 400!
Do you know what strain these are? What are you using for a reflector?
They look more sativa-leaning and could stretch significantly, going into flower. If it were me I'd probably super-crop the highest tops, rather than fim, or top them.

i don't know what they are. one was a autoflowering haze- a very good quality seed.
other 2 are hybrids- one called nepali and one hybrid which was predominantly sativa. i have forgotten the name. i can find out. these two were average quality seed.

i'm basing quality on price. one was like $10 a seed, one was $3 or something i think.
i'm using something ''better'' than mylar. entire walls coated in it. its 95% reflective vs mylars' 90% i think.
it was cheap, worth the investment i feel. i also have a hood on the hps (i guess that';s expected)
