prob.jpg This wierd yellowing that Ive never deat with and ive dealt with a variety of problems throughout my grows and i cant find a nutrient problem that looks like this. The fan leaves are doing this from the bottom up its made it up 2 and is on to the 3rd set of fan leaves. Essentially its yellowing from the outside in on each ridge of the leave and eventually leading to some redish/brown spots. Has anyone ever dealt with this or have any idea what this could be and the solution. any help is GREATLY appreciated:wall:

Ive owned jorge cervantes Grow bible for about 2 and a half years have many grows under my belt never encountered this problem nowhere in the book or on the net can i find a defficiency that looks like this using happy frog organic potting soil i had given her a few feedings prior before a rookie mistake and an overwatering problem(first time ive ever done that), the feedings before were 1/4 strength and then half strength due to in the past OG#18 has been sensitive with nutes but i guess ill try giving her a full feeding andd see if it gets any better because i do NOT want to lose it as its one of my favorite strains

Nitrogen deficiency. Only sulfur deficiency is even close in appearance and at this plants age combined with the rarity of obvious sulfur deficiency makes me say nitrogen.

I've seen this issue, a few months back. There were 17 plants in one room and only 1 had the exact same damage as shown in your pic...until the spider mites got to the other 17.

If not the case, could be a mineral deficiency...zinc?.

I can walk around my grow sometimes ill sit and stare at em for like a half hour i always check for bugs nspect each plant every day so i really dont think its spidermites or any bug for that matter its gotta be a deficiency i hope only nitrogen ill wait for a little more input before i feed her later on today

Did it happen to appear following a transplant?

Transplanted em at 3 weeks theyre now 5 weeks old 1 week into flower i also had an overwatering problem after i transpanted whihc was my own stupidity but it hasnt stopped so i feel if it were form overwatering it owuld stop like the different yellowing from the bottom up on the other overwatered plants thinking of just giving a full feeding of organic nutes unless anyone has something specific they think it could be

Phosphorous usually starts toward the top of the plant and yellows from the inside out the manganese also doesnt look like what i have as its not yellowing gradually throughout the leaf its from the outside in and the brown spots arent random on the plant they are on the ridges where its yellowed i gave a full strength feeding using the general organics line and ill closely monitor her throughout the next week its a wierd issue cannot find any pics of a similarly affected plant

What growth that is already affected will not get better. How does the new growth look? Has it spread or just the leaves originally affected? I bet they are going to be just fine. It looks like a bit of transplant shock from a pH swing or slightly hotter medium. I imagine they have already began to get use to their new homes. I wouldnt go chasing any deficiencies right now unless it begins to affect new growth or continues to spread up the plant.

Have you checked the roots for fungas? If you had an over watering problem in the past then a fungal attack could be the source of your plants problems. I had the very same symptoms a while back and went nuts trying to figure out what I was doing wrong. The plants would start dying from the bottom of the plant and it would work its way upward. I was talking to my hydro store gal and she told me to give the plants an h2o2 flushing, and son of a gun if that didn't cure it. Since then I have kept a bottle of h2o2 around just for this kind of problem. ( And kept a better eye on my watering regime ). As a fungas attacking the roots cause the roots to not be able to uptake the nutriants that the plant needs, the plant starts to canibilize the lower, older, growth to support the younger,upper growth. This resembles a variety of nutriant deficiancies, which it is, but not one that can be cured by adjusting the nutriant feeding.
I may be wrong in your case, just passing on that which I have encountered in my experiances with soil growing.

Certainly dosent hurt to look at a issue from different angles.

Is there any way this could possibly be later stages of nitrogen toxicity because the plants fan leaves at the top now have a waxy sheen to them after feeding them could the yellowing and browning of the bottom fan leaves be from N toxicity?

When you open the marijuana plant problem part of the forum there is a plant guide to toxicity and deficiencies. It's hard to see under that high-pressure sodium you took the picture under, but reading the guide I found this.A deficiency of this causes yellowing of the leaves. its common during vegetative simply because the plant is using it up just as fast as your putting it in. It also happens during flowering sometimes because most flowering fertilizers contain little or no nitrogen, as this is not a key nutrient in that phase of the plant's life cycle.
Usually the deficiency will be noticeable on the lower part of the plant, on the older leaves. then, as it progresses it will move upwards towards the newer growth.
*unlike a magnesium deficiency, nitrogen def will start from the tips and works its way inward* (ill get to mag def later). Most of all yellowing of leaves is caused by this, and it will stunt growth severely!
This is talking about a nitrogen deficiency.

Symptoms of nitrogen toxicity are waxy looking shiny fan leaves which i have Not a nitrogen deficency, Nitrogen deficient plants do not ever look waxy or shiny
