Is this septoria? Any chance I can harvest something decent?

Hey guys, this run had everything to go really well, but unfortunately the temperature dropped and humidity got really high at the end of veg. The plant on the left especially started showing yellowing leaves with some brown spots. I couldn’t really tell if it’s Septoria for sure.

Just wanted to confirm, and know if there’s still a chance I can harvest something decent :[

Thank u guys

Answer as much of that as you can. Doesn’t look too terrible. A little pale but it might be the cultivar?

Sorry for the lack of information, I’ve been a bit pissed off with this grow cycle and ended up not posting about it. I’m growing 3 photoperiod strains, 2 of them are CBD, indoor, in an 80x80 cm tent. The soil is fully organic, and one of my runoff tests showed a pH of around 7.4, even though I’ve been watering with pH 6.3. The soil seems a bit heavy, probably because I added some organic fertilizers that may have made it more alkaline, but I’m not sure.

I don’t have A/C, just a strong exhaust fan, two internal fans, and one external. Temperatures are still low — about 25°C (77°F) with the lights on and 19°C (66°F) when they’re off.

I’m using two 150W full-spectrum LED panels with LM301H chips. Humidity is generally high, usually 60% or more, and I water every two days.

I’m using bokashi, fish, seaweed, and the BioBizz bottles.

Thanks for the help!

To me, and I’m far from an expert, it looks like this lady suffered some high temperatures and rh. If everything is under control now, I wouldn’t worry too much about it. Check the new growth for signs of stress… :nerd_face:

Was gonna tag him but aint seen him in a few. Thanks @kaptain3d

Diagnosing problems has to be my weakest area of growing, but it doesn’t look like septoria to me. It looks more like a past nutrient issue, maybe related to pH. I’ve seen my organic amendments cause the run-off pH to run high but I don’t think it’s an accurate measurement of the soil pH. As long as the pH going in is right, it should be good.

I’m with @kaptain3d watch the new growth, it’s looking good from your pics. They look a little hungry to me too. :victory_hand:

Edit: What kind of medium are you using? Soil? What brand?

Looks really hungry with an early fall fade.

Runoff numbers??

Oh, sorry, I see you said you were in organic soil. The reason I ask is, up to this point I’ve been using primarily FF Ocean Forest. I’ve read and experience (some) where this soil can have inconsistent pH. :victory_hand:

As stated the soil keeps buffering up to 7.4. That locks out Zn and Fe needed for chlorophyll and enzyme production. Hence the pale overall color. Could go in a couple times with 5.8 to burn off some of the Ca buffer and test to see how that works on roots pH

TY a lot bro!!!

Super soil from “Terrô” but this run I mixed it with some other organic soils, maybe it was my fault tbh..

Heyyyy the big boss! bro, I water with 2..3 ml/l with bokashi and the tips of the leaves start burn so im not sure is she is too hungry o know? Mayt some P/F lack or unbalanced ph. I was thinking septoria but now im happyer. I´ll try to water this week only pure water with 6.3 of ph to see whats happens ^^

and ty again

Hey man,
I’m thinking this zinc and iron deficiency might be the reason…
I’ll try lowering the pH and fixing it like you said.
Thanks a lot!

Confused. Bokashi or EM @2.3 ml?

Both work to break down nutrients to make available. Causes tip burn sometimes but need clarification. Thats a really low dose either way

I got some liquid bokashi like this:

And i have some biobizz bottles, alga fish, fish, grow, top max, blom etc..

That’s EM as I suspected. Says EM on the bottle. Bokashi is the dry form of that.

Veg: 15 ml/4 L so 3.75 ml/L
Flower: 7.5 ml/4 L so that’s 1.9 ml/L

You said 2.3ml causes tip burn. I bet it does with the biobizz products.

I made this mixed soil to stop using Biobizz — it’s too expensive. I want to use fewer feeds each run and get more grams per watt, probably more than with Biobizz, like you said. ty again
