Whats going on??? Nitrogen deficiency???

Hey guys!!!
How is everybody doing?
It has been some time since i did my first grow, im starting the 5th week of flowering and the leafes on my babes started to turn yellow!!! Since they are too young to be dying from age, could it be a nitrogen problem???
Besides these yellowing of the leafes, they are doing fine (i guess), lots of cristals and stuff.
So, if you guys could spare me some of your precious time, help me out with these issue so i can have a better night of sleep!!!
Thanks a lot and take care you all!!!

Well that far into flower N is not something you normally feed your plants but in very small amounts.

What if your feeding program?

Do you CalMag Plus with your regular watering?

What is the Ph?

do NOT give your plants nitrogen, when in flower - the leaves naturally yellow, and die, as you progress thru the flowering stage - the plant is taking all it can, and putting it into flower and resin production - by the time you harvest, the plant will look like hell :jointsmile:

hey loosen up , thats natural leaf fall uve accidentally stimulated , leave it be , as the leaves fall in 3 stages , itll allow more light to penetrate plant an hit lower buds , ask ya self what happens in autumn an ull know why is goin yellow , is a feed deficiency , but if u go by the tricameral sensimelia book , thats how he suggests u gro cannabis , its a great method , but has its hold bks .

Z ....

what the plant is doing is using the natural stores of nitrates in the leaf ,to feed bud development , what ever your doing dont stop it , and remember to flush for 2 weeks , and ill guarantee itll be a wild smoke and natural , incidently ya plant pot looks a tad small , but that wouldn't effect leaf color

Thanks for the conforting words you guys!!! But...
The thing is that in my frist and second grows, around the 6th week the plants started to show these same signs! So i thought something wrong was going on. Did some research and took the risk of flushing my babes with a mild N solution (7-4-4) to see what happens!!!
Anyway, we all learn from our mistakes!!!
Ill be moving to a bigger place in a couple of weeks, there ill be able to grow my next crop in bigger pots, i hope!
In a few days ill post new picks, so you guys can see what happened with my present grow.
Thanks for the replies!!!
