Need help doing diagnosis of little ones

[cannak]

I started a couple of seeds to go outside this year and after a good start for 2 weeks some leaves started yellowing and brown spots appeared. A guy at a local hydro store told me it must be a sort of fungus, but I need another opinion. The symptoms have degenerated over the 3rd week, and I'm afraid I'll loose them and have to start over. Thanks so much guys and gals

Hi,

They need food badly. Supply them with a veg nutrient ph'd correctly and you see improvements soon!

Keep us posted!

Without knowing your medium, I don't know if this will help but...

Summary, I'm going to go ahead and guess that your medium PH is too low, locking out and thus the reason you're seeing these symptoms.

Thanks for the replies. I feel like such a noob...
I mixed some guano in the promix and thought it would feed them but obviously it's not that effective. I gave them 2 soft feeds of 20-20-20 i had in the house and they are already looking better. I gave them a trim and removed the dying bottom leaves. Hopefully they will overcome this stunt...

Will get them some proper veg nutes for the coming month.
