I have no idea what's going on here. Only having this issue with 1 plant, not the other.

Are they the leaves closest to the soil? If so remove them and see if it continues… im thinking tgose specific leaves are just not transpiring well due to lack of airflow down there but either way they need to go.

More info what ya growin in? Soil? And watering habits ?

Soil. Watering is about every 3 days which at that point the soil is fairly dry (although not too dry).
The plants were ready for transplant around this time, I went from 1 gal to 5 gal. I gave the plant 2.5 days to adjust and then went about and cut off all of the leaves that looked like this, which were most up to the top nodes, all new growth was ok. 2 days later all the top leaves that were fine prior began showing the exact same issue. This doesn't feel like a nute issue to me given that now the plant is in a new pot of fox farm happy frog, which is amended and balanced well. The root tips should be slightly traversing into new, balanced soil and so I'm wondering if this is some type of infectious process. The plant looks sickly.

Airflow is good. Humidity is a bit on the higher side at 65, VPD is 1.0 average over the last week which never gave me an issue in earlier veg in past grows.

Not the VPD in the room… im meaning those specific leave’s are they resting or almost resting on the soil. Dont forget at night plants droop a bit

Nope, I cleaned up the bottom of the plant since most of the lower leaves were having this issue. 2 days later the leaves of upper/top nodes started showing same symptoms. It's driving me nuts, about to scrap the plant but I want to figure it out first for future prevention.

Tagging in to see what Aqua and Mosh come up with. I do not recognize those spots. But based on the Petioles and veins, they do look under stress.

leaf septoria…
it’s your watering habits..

Yeah i see that as possible as well. But i also see purple all the way into the leaves. Which could be a few things involving P. Watering makes the most sense and im sure it was a major factor but i feel there is a bit more. Light to high I didn’t catch them temps but either temps to low ir at least to low at night would help explain the deficiencies also seen.

Pretty much plants were pushed to hard with light under poor environmental conditions and watering habits would be my summary

Cant help but feel ratios should be looked at also but not really a major contribution given the severity of the other factors

I've never had septoria but when I googled it was pretty close:





Not really purple so much tho so probably more than one thing going on?

Yeah i think so too… and the septoria was likely a result of the many issues that contributed to plant health. Especially as @GNick55 stated watering

I think the mod team should put together a high res photo gallery of issues with plants and causes and sticky it for reference. These kinds of posts come up daily, and I feel like the media out there to refer to is pretty poor overall. The only way I saw septoria was @GNick55 said it so I googled it.

Seems like a lot of what is out there for deficiency / lockout charts is hand drawn or low res or just overall not nearly as good as google images if you have a diagnosis in mind.


EDIT: Mods go here

sounds great @Moe.Red your definitely right, though i’m not the guy to put that together, im not good at computer stuff..
we haven’t heard back from this grower yet right? i’d like to see a full plant picture of canopy and side shot looking down, plant might be salvageable?

Started a thread here just put anything you want in there and I'll organize it with everyone's input and move it to public when we are done.

100% agree its more than likely salvageable

@Moe.Red @Aqua Man @GNick55

I really appreciate all your help. Sorry for the delayed response, I've been away and will upload pics tonight when I get home.

I don't think it's septoria, which was an early assumption of mine as well, but septoria is often quite contagious from what I've heard and the other plant in the tent which has been brushing against this one has no issue. Average VPD is floating right around 1, as I stated earlier.
I know yall were leaning toward watering issue, but I have to say I really am quite efficient with watering and have always had a good feel for when the soil is dry enough to need water but the plant hasn't started drooping yet, this is usually about every 3 days, and post transplant if the pot is larger, I will only water lightly and slowly graduate each watering toward the periphery of the pot, as to not have the plant sitting in soggy soil with more water than it can uptake.
I think it's stress related, and I'll go into some detail of the external factors that I altered this grow vs. others. I have a small 2x2 tent and growing has been just a nice side hobby, I do frequently alter variables from grow to grow because it's more of an experiment to me, I like to see what works vs what doesn't. Sometimes there isn't the 'if it ain't broke don't fix it' mentality, but it would be less interesting running on repeat over and over.
Anyway, here are variables that changed:
I usually go from solo cup straight to whatever pot I will finish in, either 3 or 5 gal. This run I wanted to try intermediate 1 gal pots.
Usually post transplant I will just place the light at the top of the tent and turn up the intensity. This time I slowly raised the light, keeping it about 25 inches from top of canopy but keeping the intensity lower (25% started and was at about 50% when this issue started. The rationale for this is I wanted to leave more wiggle room to turn the light up a few weeks into flower, rather than having the plants enter flower with the light already 100%)
Less nutrients -- I use foxfarms line of nutes and usually get a little trigger happy, nothing overboard but the tips of leaves during veg will usually have darkened (only the tippy top of the tips) and so I was trying to avoid this entirely and held off nutes. Once this issue started, PPM of runoff was about 650 and so I thought maybe I was under feeding. I did a small dose of fox farm big bloom (5ml/gal) and cal mag (5ml/gal) -- I initially thought it was a cal or mag issue and so repeated cal mag for another watering, issue just got worse. I also usually water until a fair amount of runoff so I can measure, but haven't this run because I wanted to see if holding the amended nutes in soil longer would be of benefit.
This plant that is having issues was growing very vigorously, almost doubling the size of the other and so I topped it twice, about 15 days apart. I think this was the real stressor and the root of the issue because shortly after 2nd top is when it all went downhill. But can stress alone cause this odd issues that pose as nutrient deficiencies? I really didn't know what to do to help it, so what I've done is transplanted it into the 5 gal pot (I know more stress, but at this point it was outgrowing the 1gal and I wanted the roots to grow into new soil hoping it would correct any nute imbalance. The plant would have died in the 1 gal so figured I had nothing to lose).
