Leaf septoria or nitrogen deficiency?

[Jdubb480]

I've got some yellow spots growing on a couple of my plants. I was wondering if I could get some feedback identifying the issue. Thanks in advance!

Post pictures in natural light. Looks like you might have powered mildew (but hard to tell in the purple light). The leaf spetoria has a yellow spot with a circular dark spot/burn in the center.

Updated original post. It's indoor tent so all I can do is turn on the flowering lights. Hope this helps.

Those are pictures from my microscope. I'll take some pictures with the flash when I get back.

Seeds from a friend who has been growing for decades. Cross between green crack and a Columbian weed. Home grown seeds.

4 week old grow

Plants about 10" tall

Hydro is ebb and flow one bucket I use for nutrients and it sprays the roots also rests in about 10" of water using air bubblers.

General hydroponics trio with added calmag and hydroguard.

5.8 ph checked daily.

It's ro water not sure on ppm. I haven't paid much attention to it. Also not sure on temp. Room sits between 70-80 degrees everything is in a tent. Ph usually stays the same with a slight variance up or down by a few tenths. I try to adjust daily.

No foliar spray.

I use 600w king led light. It's only running the vegetative one right now. It's about 2' from plants.

Grow tent is 5x5

Humidity is usually at 30% but when humidifier runs out drops to about 10%. I usually fix this pretty quickly. I saw one small gnat a few weeks back. Not really any other activity. This is my first indoor hydroponic grow.

Picture of setup attached.

Couple off topics.. That light probably isnt gonna cut the mustard flowering 25sqft I dont think. I could be wrong, but it sure looks awful small. In that size tent Id want to be pulling at least 4-600 true watts from the wall with LED, not equivalent watts.

Also, Really? Is this you?

You dont fit the stereotype.

Looks like a deficiency to me. What are you feeding and how much calcium?

I just flushed all my water yesterday. But I was running half the levels below.

5ml per gallon of each flora grow, micro, bloom, and calmag(7 gallons of water so 35 of each). 2ml of hydroguard(7 gallons of water so 14ml)

My apologies for not confirming to the stereotypes.

I'm not actually growing the entire tent. My grow area is about 10 Sq ft. Do you have a different light you would recommend? Or just more of that specific one? Originally I was going to have a much smaller grow area.

I was able to get these pictures. Any feedback will be much appreciated.

I also noticed my humidity was only 25%. Almost looks like some of the leaves are drying out.
