don't wanna sound like a loser but you really can feel the experience in your post, yes the def seems to have slowed hard to tell because as you said the necrosis will develop regaurdless, all my new growth is nice but seems deficiant as it appears, very light yellow anywayOnce a leaf is attacked by n deficiency and becomes necrotic it never comes back. It will continue its necrosis until it's all gone. I agree that your top new growth looks good and you should focus on it more. Have any NEW leaves turned yellow since your feedings? It looks like the problem hasn't gotten worse since day 10 in your journal when you decided to feed for the first time (which was a bit early).
I wouldn't repot an autoflowering plant and that should be big enough for that autoflower to finish out.
Watch your new growth and maybe try some basic foods like Jack's Classic 10-10-10 for a couple of feedings. It's a good balanced cheap ass nutrient solution that works well in soil. You have or had a little N def. and it will help, but you don't want to off adding 5-0-0 feedings or anything buck wild in there. Some decent soil and some 10-10-10 will give you some good results. I think your plant is already recovering and you are looking for a sign you aren't going to get. The sign that it's recovering is that it's not getting worse anymore. Primarily that the problem is not attacking new growth.
lightly, what like 300 PPM?glad u chipped in lasrbrn. i would foliar fedd lightly an npk (with lil bit of p-k only). give that a try.
well all my stems and veins are red isn't that also a mag def symptom?, on the root sppace issue I just repotted so shud be good..I experienced what seems to be the same problem. It first off is not an N problem although i thought this initially myself, so i would skip foliar feeding. im pretty sure it is an mg problem, the only other thing i can think of is that autoflowers are said to need a lot of root space. Anyways i was pretty certain my water was way to high in minerals (esp. calcium) and this caused a lockout of Mg+ (or fucked it up in some other way, im no chemist) So i repotted and started watering with plain gallon jugs of water from the store. Few day later the plants looked amazing and the leaves even regained a green color (except the crispy parts it looks like you have too). Unfortunately i dont have a ppm tester to check my water so i cant this this is the absolute cause but it worked. I think autoflowers are really sensitive to this because i had a non auto plant that didn't seem affected but this was from the last batch. Hope this rambling helped and that your plants make a turn for the better.
I cannot get zerowater, closest I have had is 105 PPM, so it will be 200 PPM NPK and foliar feeding just a light spray,Thats y i said it may not be a n problem. Heres the thing. Pure water with some great npk although light like 5 ppm water and 200 ppm npk, u might see the upper part darkin up. Yes pure water is always better. No one will really ever know, so dont expect someone to give an exact answer. U just have to try a couple lil things and when u do make even the lil move, make sure u space them out to find out what worked. Sprayem lightly with what i said and give it a couple days. I spray when lights go off and wash(just water) the leaves right before lights come on. To be sure, use a all around nute, something with most essential elements.

thanks for the input bro

you spray lights off?, isn't that perfect for mold mildew to form??
I have fed twice so far @ day 27 of an average 60 day life span a 400 PPM then 500 PPM feed,That should give us a good start.
I feed my autoflowers Molasses and I dont see this in your mix, adding this will not burn or anything and may help, always judge by new growth as suggested before as well. Let the soil dry before feedings and maybe add some molasses. Is it growing again after repot? guess too soon to see would let it dry goodI have fed twice so far @ day 27 of an average 60 day life span a 400 PPM then 500 PPM feed,
I am using Bio bizz all-mix, it burned them a little very young but showed very good even growth until the def,
waited 7 days in total for improvement,
I repotted today only because I got roots @ the drainage holes!,
I am using bottled water with a starting PPM of 105, assume it has mag?,
may have overwatered a little in a rush to feed after a between feed watering,
yea there is a few "rust spots" but I think that is from spilling water with pH down in it on the leaves..,
I have lost the three biggest sets of fans to this def and the WHOLE plant is pretty yellow even new growth..
THANKYOU VERY MUCH
this is right^^^ the biggest mistake you can make is overfeeding your plant trying to correct the problem! generally this ends up creating more problems than anything. i had the exact same problem last year! looked identical to yours. had two different plants do this. both just needed re-potting! (well i repotted one into a bigger 8 gal. container and put the other in the ground.) solved the problem on both of them. i'm telling you this from experience. not guessing. i looked at the pic you posted and i can guarantee you that if you repot you'll see how the roots are at the bottom of ur pot and are starting to brown/rot! those bottom leaves will fall off eventually...but you'll see a definate difference in your plant(s) after approx 3 weeks to a month. they'll start greening back out and returning to normal after u give those roots some room to breathe/grow in!i think she needs re-potting
I got roots, they were bright green and in perfect condition so I repotted..this is right^^^ the biggest mistake you can make is overfeeding your plant trying to correct the problem! generally this ends up creating more problems than anything. i had the exact same problem last year! looked identical to yours. had two different plants do this. both just needed re-potting!

I think we are having a communication problem here:no smart ass, i said "repot and you'll see a definate difference in your plant(s) after approx 3 weeks to a month."
