Somebody help Please

The first two are of a Sour D plant and the others are U.K. Cheese. They're both about a month into flowering and have been experiencing these leaves that start yellow then the edges and tips turn brown and finally they curl up and die or fall off. My first instinct was that this was nitrogen deficiency because that's what my last grow suffered from but when i feed them a high N fertilizer it doesn't seem to help. I use the Fox Farm brand Fertilizer and have just recently flushed the two girls. They don't seem to be improving any thoughts?
Thanks anything helps

if you want pics of the whole plants i can provide them too

i would remove the top couple of inches of soil, this i think is whats causing nitrogen lock out...

thanks. would that really help?

it helped me when i had similar problem, apparently the top couple of inches builds up with salts..
hope it works for you.

can i see the whole plant, please?

yeah hold on

looks like a ph problem to me. have you measured yet? i would hold off on digging out any soil until you find out what your problem is. a matter of fact that is the first time i've ever heard that advice. not saying it is wrong, but i would read more into it before i did it. good luck, kevin

thanks kevin, i measured the soils pH and its perfect but my water might be a little basic
and as for the pics i might be able to get them up later but not now cuz my camera is with someone else and its night time anyway
i will post them asap

i'd probably just say it needs nitrogen, or some bloom nutes.

I had this same problem the first time I grew my own. I freaked out. The truth: don't worry about it. I soon realized that this just happens. I almost always have a few leaves or stems do this. It's hard to see something you love so much experience pain like this I know. I once had a plant that had all of the leaves turn yellow and die and I decided to leave it anyway when I started flowering. Two days into flowering, this same plant shot up inexplicably and grew taller and fatter than my other 3 plants. The rest of your plant looks great, just snip the stem off, or leave it and don't worry about it. It happens.

Mine were lookin similar to yours n i gave them a dose of nitrogen n now the leaves look alot healthier.. They are in the fifth week of flowering but that could be normal for that age.. Not sure..
