changing lights during on day 40

i recently bought a new light both from same company but they really are two different kinds of leds. one has cob cree led and one is running samsung and osram leds the one im using at the moment is the Solo 400 from hortibloom

i recently bought the new 2023 mega evo 720

would switching to the new light on day 40 when it arrives be beneficial. all posts I've been reading the guy asking the question is always trying to replace a hid light with led and is always trying to replace there 600 watt light or 1000 watt with what they think is more power in led by end up being way less. in my scenario im pretty sure the new light is almost dbl fairly certain the solo 400 is exactly that a 400 watt light. i just don't know wich leds are better and what led drivers are better between the two

Definitely change to the new light when you get it. It's a much better light. Just turn it down to 50% power or so when you first change it. Then turn it up as you go.

New light looks much promising but be careful not to burn the plants

Get a par meter. My switch to LEDs was shaky and getting a par meter changed the game.

well I'm pretty sure i stressed my girls with my new light i switched to last week 360w cree cob solo 400 to mega evo 720w with Samsung and osram leds. is this possible? in one week time to see nanners under my buds and seeds to start forming. it's hard to find out info on life cycle of seed from polination not germination i just know they were not there before i know my clone that was growing two weeks before i started the other 4 on 12/12 ended up having naners as well and fully mature seeds. the plant i got the clone from is not a he/she yet my clone turned into one. should i just pull them out and start with more girls or just let them finish two are sativa based one being super silver haze wich can take 12 weeks to flower fully. the other 2 i know names for are hurricane and wedding cake. i also forgot to turn light down to 50%
