(pics) Yellow veins?

One of my plants has bottom fan leaves are green with VERY yellow veins. The leaves are slowly turning completely yellow. It's working it's way up. The new leaves are even worse. The buds don't seem to be stunted but they are yellow. There is no sign of burn/scortched margins or tips. I tried to do a search and only found the opposite "yellow leaves with green veins" So what does yellow veins mean? I thought it was a over fert problem and flushed it good but it only seemed to slow it down. I am thinking nitrogen deficiency but the new growth isn't stunted, just yellow.

That pic is really fuzzy but I dunno, it looks like the intraveinal regions are yellow.

better lights maybe?

use distilled water to keep your PH at the right level

wat kinda pots r u using?

I'm not sure but when veins are yellow it means that there's some type of deficiency, you might wanna look up on that.

looks like ya have been overwatering
and it does look similar to a magnesium deficiency i would use some epson salt which can be aquired from a local chemist when using epsom i use half a teaspoon to 4 litres of water
good luck
cheers all :)

I know with my gardenias, when their leaves look like this it's telling me it wants more iron. I don't know if it's the same with cannabis. I did folar feed her on Monday with epson salts. She doen't look any different. I am not sure if I should be folar feeding anyway since she is week two of flowering. I doubt its good for the buds. Should I try giving her more epson salts? Hes soil is still wet from when I flushed her a week ago when I thought it may be overfert.

Why would you give epsom salts if you think your plant needs iron?
E-salts are a magnesium compound.

You know right that yellowing low leaves are normal in the flower time?
TOTALLY normal.
The lowest first, showing signs of N deficiency which is linked to and looks like Fe deficiency (good for you for having other plants to compare to!!! Yay, gardenias!).
Because when you switch to flower nutes you withhold Nitrogen.
This is normal, and it will get worse.
If you want to prevent it without messing up your flower cycle by giving the wrong ferts, mix a little fish emulsion into the soil before you transplant into the flowering pot. It will slow down the dying-off process fo the lower leaves.

Sorry, brain fart on my part. I meant magnesium deficiency.

BTW, I read in my book that some yellowing is normal but ALL her leaves are looking like this especially the new ones. Unless all the leaves are suppose to turn yellow, I doubt it's normal. She is my oldest as well as my first grow. So I already f***'d her up twice. She has been flushed twice because of my F ups.

I guess I'll do what busteruk7 said and wait till she's dried out before doing anything. She'll probably completely yellow by then. You know, I have always had a green thumb. I never had any problems with anything in my garden I couldn't handle. This cannabis growing has really put a dent on my self esteem. I quickly learned they not like any other plant. Hopefully I'll learn from my mistakes and do better on my newest batch.

Thanks for the advice
