Magnesium deffiency ?

looks like N def. to me

no do not use regular salt, regular salt is sodium chloride, and chlorides are not good for plants. epsom salt is magnesium sulfate. two very different element componds.

anyone else think its nitro deffiency ?

I have in front of me, Ed Rosenthal's The Best of Ask Ed: Your Mãrijuana Questions Answered. On pages 256-257 there are side by side photos of nitrogen and magnesium deficient plants, and I still have a really hard time telling the two apart. From what I've been reading on Mg deficient plants, the yellowing starts at the edge of new leaf growth, then spreads to the entire leaf leaving only the veins green.

I wish I could see a close up of a single leaf, but going off of the photos posted, I would agree with rmckenz85 and smallclosetgrowr. I suspect nitrogen deficiency because the yellowing appears to be spreading from the center outward. Just to be safe, go to your local garden center and pick up at $4 soil test kit.

alrite man thanks for your help ill go take some photos now of close ups and where its spread

check this out the first pic I put up is Mag problem the second is Nitro

hard for me to get something of those pics the second pic the leaves are allready dead so i cant see what happens and the first pic i cant see that much just a tinge of lime foliage

rofl i just relized that this plant is just starting to flower so ive probs got nothing to worry about lol , thanks for the input guys , i might just give her one more hit of nitro what u guys think ? or get her on bloom nutes asap? keep in mind shes only just started to flower but shes lost fucking heaps a bottom leaves , maybe 6 huge ones is it normal for that much foliage to yellow this early ?

nitrogen, it needs a few doses. give it a full dose along with the flowering nutes. do this 2 to 3 times and it should be fine. never mix the 2 nutes first. add water then nutes. stir. then add the other nutes.

wouldnt that be over kill ? u want me to give her a normal dos of veg nutes and then mix a normal dos of flower nutes , im thinking it will burn her

no he means the next few feedings add extra nitrogen

you could do half doses of each at first. i often do full doses.
