Help leaf septoria 3 weeks in flower

[Luckyfrank]

Does anyone have any idea what I can do? I stripped all leaves that had the marks on it a few days ago and now slowly it’s spread everywhere. I’m absolutely gutted it’s getting everywhere attacking all the leaves apart from the small ones by my buds. Is there anything I can do, I’m using a bran new iws system which I’m thinking will need to be binned after this disease as I imagine it will have infected everything.. help

It's not Septoria but it will devour your whole plant.

I'll let someone else tell you what it is because I just can't deal.

not septoria, not a disease, it's a deficiency. what is your vitals? medium, nutes, water, temp, humidity, type of lights?

hey dude I’m using iws flood and drain, 60/40 pebbles and coco

I’ve been feeding cannacoco a and b at about 1,4 / 1,6 and just upped it to 1,8.
I added calmag at 1ml/1l about 3/4 days ago after giving it a flush

temps are 26/27 max

and rh around 40/56%

I’m growing under led 600w Zeus pros

Never had anything like this

any advise would be great

I'm not an expert on coco, but I believe you need a lot more cal/mag. did you condition the coco first?

no I didn’t I never have

What’s that man

 

[Luckyfrank]

It’s my first time using led. And I’ve never used calmag before, I’ve been adding it for about 4 days now and it’s not getting better

 

[go go kid]

What’s that man

phospharus deficiency

 

[Luckyfrank]

if you didn't condition the coco first, you could be experiencing lockout. but I bet you are also not adding enough cal/mag. Really,, google growing with coco and start reading.

Il have a read. Never had this problem before mind when using hps lights

 

[Luckyfrank]

yeah, led needs a higher temp and more nutrients over hps, you need to relearn how to grow with led

Nightmare I thought all my problems were going to be solved lol

here is a good read

Deficiency using COCO + Led Strips??

Hey Guys! I haven't grown in COCO for a while since i've been running aero, but for this grow i had no choice but to go for the COCO/perlite route. That said, i seem to have a deficiency in all of my veg plants. For this tent i'm running 150W of 3500K Bridgelux Gen2 strips I'm trying to clear...
