Septoria Leaves or phosphorus deficiency? HELP PLEASE!

[Tonino]

Hi,
My babies are 3 weeks into vegetative and are showing symptoms which include small spots on the leaves which were light green and making that part of the leaf very thin. Then they turned yellow and now brown and dry.
Before the plant had problems of nutrition burn (which can be seen by the dried leaf tips). I think it was nutrition burn and was douting that maybe it’s nitrogen deficiency.
Could anyone help me telling me if they are having septoria leaves or if it’s another problem like phosphorus deficiency?
Any help is much appreciated!
Thanks.

There are no bugs at all
Checked everything seems normal. What could be the reason of these spots on the leaves?

Ive had this before. Its not septoria. It is some type of fungus though. Thats the answer I got from people on here. Maybe somebody else knows what it really is.

So what did u do to solve it and what happened at the end?

I believed I was watering too much (coco). I took a gamble and kept my routine. It never spread it only stayed on the two leaves I found it on. I harvested the plant awhile back and noticed that the "fungus" spread a little more on the same leaves. Its up to you. Do more reasearch as to what it could be (I never did because it was only on one plant). I would be worried if it was on all your plants though or all the leaves.

I believe mine started with roots staying really wet this Spring with temps staying down to 35 at night. Plants do fine above ground.

But what treatment to use? Did you find out what was on your leaves?

Mine actually was probably septoria. Basically treatment is the same for most fungus. This plant was halfway through flower. I didn't want anything systemic.

• 1 gallon water
• 1 tablespoon baking soda
• 1/2 teaspoon castille soap
• 1 tablespoon horticultural oil

I got All Seasons horticultural oil because Amazon ships to Alaska. I live too far from a city to go shopping Lowe's would have it.

I remember I had septoria on a plant indoors now. I used "Actinovate" a biological fungicide. I would recommend that to the OP now that I think about it. That or "OG biowar."

I had never had it. Thought it was a calcium deficiency but I use cal mag regularly starting in veg.

It's time for all this septoria bullshit to end,look at a reliable leaf chart and then at the"Marijuana Garden Saver" book.Septoria requires certain conditions that should never exist in an indoor garden!Find the true problem and stop blaming one thing as the cause of all problems!

My first thoughts were the leaves are very dark green, what are you feeding? Also to check for bugs which was addressed above.

septoria would not be my first impression, but that doesn't mean it's not septoria. I'm assuming your humidity is uncontrolled ?

.. here's a few pictures, hope it helps

Good luck!

I am feeding Bio Grow of Bio Bizz (4-3-6). The leaves were very dark green but they have been lighten up and now they are normal green. I cut those parts of the leaves just to be sure and I still haven't got them so it seems that I'm okay now anything it was.
My humidity is more or less controlled. I just make sure it's between 40 and 60. And in vegetative as high as 60 is nice, no?

how did you apply this?

 

[hotrodharley]

how did you apply this?

Spray foliar. Tops and bottoms of leaves.

That plant that was showing the symptoms is completely healthy now and growing fast! But the other one is showing some strange signs and I think this time is closer to Septoria. Unfortunately in the last two days the humidity was around 65% and I couldn't control it since I'm using a very basic setup and don't know how to reduce the humidity, any ideas?
Anyways as I expected that some fungi are growing I cleaned the suspected leaf with mixture of baking soda, water and soap. Could someone please help me and tell me if I'm getting septoria? (There's one small yellow/brown dot behind the small leaf that I'm holding in my hand and also in the front, the one on the left.)

P.S. The white powder that u see on the leaves is the baking soda I applied.

Just let it grow. Plants have small issues when they are young that 99% of time time dont make any differance, while fucking with it can hurt it. What's in your picture is a non-issue. Except it's looking a little over fed, but again, dont stress out, dont go waste money on this or that.

Make sure your allowing proper dry cycles for the soil, make sure it's not too hot, an let it be.
