Lights per strain.. jack-47 deadhead OG

Wasup everyone. I have feminised Jack-47 which is probably pretty easily spotted as Jack Herer x AK-47, from Sweet seeds. Feminised Deadhead OG this is a Cali Connection seed and it is SFV Kushx '991 Chemdawg. I also have Critical Mass AKA Big Bud from Mr. Nice Guy, I'm excited to try these.
(5) regular kandy kush x skunk #1, (6) G13 x ?,and (6) feminised White Widow which were free gifts from Seedsman.com .

This will be my cherry popper grow So my question is, which of these should I do? If you have tried these or similar strains or know about growing different strains together, sweet.

Also I have a t5 and mh for veg how soon is too soon to start with the 400 mh?

Much love- Jack

Jack,

I can say that the Seeds man White Widow should ask to be fed an N solution between 2/3 weeks, so watch out for that initial faint yellowing.
That it responds well to F.I.M/Topping/LST, so take advantage on whichever method you choose. And that you'll be good throwing them under the 400w after about a week.
As long as they're not too hot under the light it doesn't really matter.
Can't speak on anything else your growing, but I'm 45 days in w/ a Seedsman White Widow.
Good luck with the grow bro
