I would say a slight iron deficiency. Probably from high ph.
LOL! WHY can't it be?It cant be iron deficiency as that starts with new growth first, this is the opposite it seems, and its the entire leaf slowly turning yellow rather than from the edges or spots. I notice it a bit on the ak as well but with the big fan leaf on the bottom. The upper part is darker green. I just wasn't sure if the white widow can be lacking nitrogen at the same time as displaying the claw from a previous overfeed. I assumed as it used up the excess nitrogen, the claw would go away. Im not sure what to do, I probably will only water them. If the leaves turn yellow i'll cut them off.
WELL SAID!!!As one mentioned earlier - AUTOS ARE FINICKY - Some strains CAN tolerate LST and some cannot.
Most AUTOS form into the typical APICAL shape ( xmas tree ) BUT ........
Some hybrids CAN be manipulated ... Heavy sativa dominate strains can be LST ( meaning LIGHTLY SHAPED - or " opened up for light ".
AUTOS HATE STRESS ..... TRANSPLANTING , TOPPING AND SUPERCROPPING CAN DROP YOUR YIELD GREATLY .
AUTOS ARE MOSTLY " PLUG AND PLAY " ... Just plant and harvest !
Sativas can be trellised as an alternative to LST.
Indica autos are usually more squat and bushy and can be " opened " up a little.
Autos " do not have the time to recover from injury or stress " ..,
They go thru a short veg from seed - usualky ( 4-5 weeks ) and then it will MOVE INTO PREFLOWER whether you want it or not. Its hardwired to flower ON ITS OWN.
Thats why it is best to grow on NO LESS than 18/6 or better. If you grow on 12/12 you making the descision before it can VEG as best it can on its short life.
Right there .... you stepped on your dick and cut your yield ...
Why over think these ?
HERE IS HOW I DO THESE NOW ...
I just pop seed into a premium mix .....
I water ONLY ........... For up to week 6 or 7
( this is where my soil shows a little depletion )
THEN i begin a Bloom feed during these Critical weeks for Bud Building !
I feed for 2-3 weeks ( depending on strain ) then back to water.
No burns , no strange stem colors .... No drama.
The following is an AUTO JACK HERER .... On the WATER ONLY regiment.
These are early pics and she is now 4-foot and beginning preflower
( i will update with pic )
I still am just giving water. It is going into week 5 .
All green , no problems.
She is more sativa dom with wide branching and more narrow leaves then what the early pics showed.

YES!Thanks for the replies..unfortunately the main question, like always, wasn't answered...can a plant display nitrogen toxicity from a previous feed, yet still need nitrogen now? The rest of the things, including all that's mentioned in the prior post, I have read over and over a million times. All I wanted to know is can a plant show the claw and still be needing nitrogen. I found the answer elsewhere, thanks all, no need to get another thread completely off topic
LOL..like most threads..no one reads! All the info is on page 1 post #1! lol..question was answered days ago..thanks again.LOL! WHY can't it be?
From pic 1 to pic 4 you are showing a slight Ir and maybe some S def!
While I would have added some more feeding at pic 1.....At pic 4 I would look to add a kelp extract and keep using it for everything it brings to the table! Not just micro's!!!
So, how about you tell us what soil?
Did you do anything to the soil?
What are you feeding?
How often and how much?
Any supplements? LIST them please.
What water?
pHing the feed and or water? To what?
I might supply these answers before my Dalek "friend" - "exterminates" you!
