Hello B I don't know about the effect of nutrients I'm affraid but I think that inducing flowering soon would be a wise idea
As soon as you can identify the boys then that will give you more space and you will need it they are going to get a lot bigger yet

As for the grow itself B, I like it ................. you are doing a great job

mand Reviewed by mand on . MY SET UP 1ST TRY Hello I I'm having a heat prob, I got home from work and my closet grow room temp was 109%F with a 3ft fan moving air around in the closet by the way i have a 400wMH. Today was the 2nd day with this set up yesterday it wasnt as hot I think the outside weather had a lot to do with that being that it wasnt really cold today. But my question is should I install an A/C in my closet (its a window a/c) cause i dont even think 3 fans would do any good :confused: or should i get a 250 MH the Rating: 5
