Fan Leaves Turning Yellow :(

Hi Guys,

Have a WW tat has been flowering for about 2 weeks. The grow had been going very well and plants looked extremely healthy going into 12/12. However now the plants seem to be turning gradually paler and from the bottom upwards the leaves are turning yellow and dying off. I know that this is normal to some extent during flowering but this seems much worse than normal and is affecting all growth not just the very bottom leaves. Even the new growth seems quite pale. I decided to flush them well today in the bath in case it was salt buildup etc. Anyone got any ideas? Really dont want it to spread to the whole of my plant!

I have seen lost of posts asking for answers, there is , firstly a thread wich deals with plant problems such as you describe.
Second, nobody can really answer youre question faithfully unless you put up all of the conditions, grow room, lights, nutes, etc:- present and past.
Sorry dont mean to sound rude but all info. is needed unless you want to atrract someones guess, I would ignore them though!!

what size pots?
medium?
watering schedule?
feeding schedule?

let me know as much info as u can and i will help u get those things better

Sounds like classic nitrogen deficiency.
