Low Nitrogen Causes Males?

I am doing flowering now. 12/12 and switched my nutrients to the GH bloom cycle. Which requires no nitrogen in the mix. Will this cause more male plants?
 
Some say that yes low nitrogen will create more males in your garden

And some say that grinding up your wife´s birth control pills and feeding with that creates more females. Both hokum.

Sex is predetermined in the seed - this is why I pay a premium for feminised seeds.
 
Looks like you and I read different books huh
but the guy who wrote my book knows a lot more than you,
but he might not be right so that's why I said some say

How old are your plants? Sex is determined during week three of vegging. No nitrogen in any bloom fertilizer will give you yellow leaves. Personally I would never use a bloom nute with no nitrogen and twice during flowering I give my girls a healthy dose of fish emulsion for the extra N.
 
The sex of the plants should have already been determined at this stage. Can you see any pre-flowers?

Sex shows around week three, but is determined in the seed.

1 male chopped it down and smoked it.
1 other suspect male.

Those where my two BIG plants.

the other 2 have no hairs but no balls neither. they are much smaller not bushy and taller they look more sativa-ish. I named one of them Retard because it was serverly retarded at birth. I thought it was dead. I even made a thread back a while https://www.rollitup.org/hydroponics-aeroponics/350612-she-dead.html go look and laugh at it.

A seed has no disposition to be one sex or the other if it's a regular seed. If you were to buy a pack of ten regular seeds, the sex of the seed is not already determined. Your growing environment and what you give your plants will determine their sex. It's not like the seeds are sitting in the pack and one is thinking, I'm going to be a male, that's not how it works. The sex of the plant is determined by the seed but it's the surrounding environment that affects that determination, not the seed itself.
 
Sex is predetermined, this is why I buy feminised seeds. But there is obviously an awful lot of confusion on this matter.
 
Ive heard it but dont believe it since Ive seen alot of N deficient plants turn into the finest lady ever. Until I see it firsthand or read actual scientific proof....Its a myth In my book. I dont really read books on growing. I grew and learn as I go and I must say, Ive learned alot just from my good friends here at RIU.
 
Take 10 regular seeds, give them all EXACTLY the same growing environment and you will get, on average, 5 boys and 5 girls.

That is the ratio that everyone speaks about, fifty/fifty. This grow I've started ten plants, got seven females. Last grow with regular seeds, started ten plants, got ten females. I seem to average around seven out of ten female.

This is from Jorge Cervantes, environmental factors start influencing sex the moment the seedling has three pairs of true leaves. Increasing nitrogen levels makes more females, lower levels create more males. Lower levels of potassium creates more females. A higher nitrogen level and a lower potassium level for the first two weeks increases females. Low temps, more females, higher temps, more males. High humidity, more females, low humidity, more males. Low moisture levels in your grow medium, more males. Blue light, more females, red light, more males. These notes were taken from Henk, the owner of dutch passion seeds.

If anything, you want more nitrogen when you flip the switch. Then when the stretch stops, make sure you feed something like 1-3-2
