this happens everytime, yellowing leaves with dark veins

i have done a fiew grows with realy good results, im happy with what ive learnt apart from each time i grow, come week 4-5 of vegg 2 week2 of flower the older fan leaves and some other older leaves turn yellow while the veins remain dark green, this hasnt caused a problem before but i wanna kno what it is??? any1 had the same or recognise the symptoms??

i wonder if that effects yeild or quality of the finnished product, the new growth and leaves around the buds are all looking awsome!!

sorry cant do pics theyr sleeping.

feel free to post away guys. taffo

I just transplanted a couple of mine into bigger pots 3 days ago. Day 2: Tops of plants sagging down but come night time they rose back up...weird http://img12.imageshack.us/i/001jql.jpg/ http://img11.imageshack.us/i/002iae.jpg/ http://img44.imageshack.us/i/003oqi.jpg/ http://img5.imageshack.us/i/004xpd.jpg/
Day 3: Fan Leaves are turning yellow at bottom. http://img132.imageshack.us/i/002ruf.jpg/ http://img188.imageshack.us/i/001kkk.jpg/ http://img188.imageshack.us/i/003mfo.jpg/ http://img188.imageshack.us/i/004vvf.jpg/ http://img44.imageshack.us/i/005baq.jpg/

can we get back to my question, sorry m8 but ur distracting the attension off the subject of my question, i dont mean to offend u m8.

can any1 shed some light on my problem, then if we get it sorted well all chip in and help this fella out 2???

Im kinda new still.But yellow leafs on or towards the bottem mean not enough light reaching them,might as well cut them off.East,looks like something fell on the top youre plant lol.
This is all just from what ive read being on here as long as I have.Taffo,idk relly if the veins are still dark green.Put more light to em & see if they pullout.But usualy once theyre yellow the leaf die anyway.

again i dont mean to offend u m8 but im looking for experienced growers to answer, i should of stated that its my fault, if uve learnt anything m8 u should avoid cutting the plant unless completely nessecary.

can any experienced growers help me on this 1, like i said its not realy a problem as proved from the previous results i just wanna kno what it is to see if sorting it will improve my end results even more, thanx and please boys(the first 2 posters dont get offended by me asking for more experienced answers, thanx) peace

Is it possible that the water being used for the grow isn't in the proper ph levels? Could this be the reason for the yellowing?

I'm an inexperienced grower but got quite lucky in this area, (as my tap water is at a nice 6.8ph).

Well yes you actually can cut the leaves off once theyve gone yellow...like canefan said it emphasizes growth to the top.

my tapwater is the same !! my soil is slightly alkaline, only slightly. it happens everytime but doesnt realy effect snything i still get massive dank buds, i was jst qurious what was doing it realy, i think it is a slight nitrogen difficiency and maybe a bit of iron also!!?

This will go on forever man take some pics.

Zinc Toxicity:
Excess Zinc is extremely toxic and will cause rapid death. Excess zinc interferes with iron causing chlorosis from iron deficiency. Excess will cause sensitive plants to become chlorotic.

does this look like what your dealing with?

m8 thats the same pic as what the chap posted below, as ive stated a fiew times now the new growth is fine, its old fan leaves that r effected, maybe its just a slight n difficiency coz the babies r starting to flower, its natural to happen like that i understand!!
