Looking for second opinion

[Antman603]

So I have used both a slurry and runoff to test ph and it is around 6.3. I did have a bout of overwatering as I am using new soil that holds moisture more, but i have that under control now. I am using fox farm trio nutes with 4 tbsp of the general stuff and 3 tsp of nitrogen rich every other water. If you want any other info just ask.

I'm looking for a second opinion on if this looks like leaf septoria or not. Based on my research I would have to cut off a lot of fan leaves if it is and that's definitely not something I want to do if it isn't. Just looking for a second opinion before I start chopping and deep cleaning.

All the lil spots look like bug damage, imo. I could be mistaken though.

Have you scoped the leaves to rule it out?

Damn. What causes that?

That's a pic of leaf septoria from GrowWeedEasy. I don't know if that's what the OP has though. He should check for bugs too.

Ok, I was kinda assuming that's what it was, but I never seen it before. Does it only affect 1 leaf?

I've never had it, but it sounds like it's more than one leaf usually and it spreads fast since it's a spore. I haven't done much looking into it though.

It does kinda look like spider mite or thrip damage, but I haven't seen any webs, and the underside of the leaves look clear. I could try putting traps in the tent to see if anything sticks.

Webbing is the last thing you'd see. And you need a microscope or something to see spider mites.

Ah, ok yea I've never actually had spider mites before. It probably wouldn't hurt to put some traps in or maybe just hit it with insecticide though. Definitely wanna get this figured out before I flip to flower, which I was hoping to do pretty soon.

Try to clear up any problems before flower. USB microscopes are pretty cheap, or you can get a $10 loupe. Some cellphones can zoom in enough now too.

I'd try to find the issue before you start spraying a bunch of stuff. But another option if you decide to spray is citric acid and water.

First …. Zero need to feed every other watering. That is a sure fire way to overnuting the medium and plant.
‘Most feeding will last at least a week as it becomes available to plant. it’s a waste of product.

Second …. Stop slurry testing and trying to gauge runoff … tail chasing.
‘As long as your water and or feed mix is ph’d to the plant as needed then all is good.

Third …. Clip off all “ suspect “ leaf. See if issue returns and or becomes systemic.
‘There are plenty of “ garden safe “ fungicides out there for preventative use.

Fourth …. STOP WATERING EVERY OTHER DAY.
Wouldn’t doubt the excess moisture isn’t contributing to possible fungal issues.

First point. Only reason I'm doing that is because this soil I'm currently using drains very slow. I'm watering once every 5-6 days now so I'm feeding roughly once every 10-12 days. I probably should have specified that

Second point. I have still had issues where I properly pH water and it runs off a different pH than it went in. In most cases it is as you say though. However, making a slurry/checking run off is pretty quick and helps me checkmark some boxes so I can move on to other things.

Third point. Yea this is why I wanted the second opinion on if it was leaf septoria. If it's simply bug damage or nute deficiency then cutting the fan leaves off would be unneccessarily hurting the plants growth. Although, it might not be a bad idea to cut em off anyways and see what happens, especially this far along in veg where it wouldn't be the end of the world to cut the few problem leaves off.

Fourth... I stated in my initial thread that its new soil I haven't used before and it drains slowly. I was watering once ever 3-4 days, and the plant showed clear signs of overwatering, so I fixed it. However if it is leaf septoria, you are definitely correct that this heavy moisture environment is what allowed it to cultivate

Ah I have a loupe, I could try using that. Also, thank you for the natural alternative suggestion, those are always nice to know. I've used a basic dish soap water mixture before, never tried the citric acid one one.

Roger that on issues with drainage. Your dry back period should tell you when to water again.
Still think some fungicide prevention could be helpful.

I'm sure I could look it up, but do you have any natural fungicide concoctions you prefer? Or would you suggest a more chemical approach?

I use Regalia

I use Regalia

Regalia CG Biofungicide, Fungicide, for powdery Mildew, inhibits fungal and Bacterial Disease Boosting Yield, 0-Day PHI, 4 Hour REI, OMRI Listed (1, Quart) https://a.co/d/fflSdpu

Shit is expensive. I use citric acid too. 1 1/2 tsp to 200 ml water. Add 1tsp h2o2. Don't go too crazy on the mix, you'll burn the shit out of the pistils.

On the second point about pH, the input and runoff pH are going to be different, due to nute concentrations, root exudates and respiration. Those factors are never consistent, meaning your runoff pH will never be consistent. Imo, it's useless and will probably cause you to make unnecessary changes to the pH. Just my opinion though.

Just remove all the affected leaves and carry on. Those lower leaves arent doing anything useful.
