the fastest way to know is putting it into 12/12. that way you will probably see the sex within a week. afterwards you can just switch your lights back to veg hours :P
The door will probably have to be open unless you have a ventilation shaft in there? some closets do. for intake get another fan thats a bit weaker or use passive intake. best of luck to you!
i vegged thru a whole veg cycle with 16/8 with no problems at all! they grew a bit slower tho but still good. i had 5 different strains in there and only good results.
it looks like you dont know anything about cool tubes. yes there are bad cooltubes around. very bad! but if you pick cooltubes with the correct type of glass+ reflector you wont have the type off loss you described. its all about what material is the cooltube and how they put the reflector ...
i gues it depends on how good your ventilation is. but with only 1 fan pushing out air it probably would get preatty hot or you would have to have your light preatty far of. i have a DS60 and if i ran a hid light in there with bad ventilation i think it would get preatty hot.. but i never ran...
cooltubes are not "poor" lol but yes cooled hood's are better but more expensive. A cooltube is preatty cheap + the area he has to fill is small so the light losed because of the cooltube is nothing compared to how much closer to the bud he can place his lights. getting your lights closer is ofc...
look like nutrititent def? maybe it ph lockout. and yellowing leaves is probably N def if yellowing starts from bottom up. when areas in between the veins of the leaf start yellow its time for mg. the red stems on your leaf indicate lacking of P. and so on.
I used biobizz and tbh i must say...
just take all the clones you need bro. since you wont take new clones from them and they will get at least 8 weeks to recuperate i see no problem with taking a lot of clones even if it would induce a bit of stress. my clones are cut to fit into my dome and they are usually about 5-15 cm.. 12...
Start the count from day 1 of 12/12 and dont go after breeders recommendation ever. get a jewlers loupe and check trichomes. try to get close to 100% cloudy as possible and stay away from Myth amber trichomes. ive had 2 plants of the same strain have 4 weeks difference in finished flowering...
Let me see if i got this right : you have theese two plants on your veg area with 400w MH and a flower area the same size with 400w HPS that currently is empty?
my tip would be this : try both
1. take enough clones to fill out your flower area
2 use your entire flower area and run lights 24/0...
11 years old given to me by a old grower. if you just store them right i would say you can keep them forever? or maybe you peopel never heard of the global seedbank on svalbard and those cinds of places :)

Big Buddha Seeds Super automatic sativa and critical mass automatic - This is some truly good genetics :P

oh and once i broke a top straight of (4weeks flower) and it was hanging in one or two fiber hairs. taped her together and elft her alone. when i cut her down at week 10 the top had grow back together with the stem :).
