First time grower, yellow/brown leaves during flower.

[Lastwish]

Hello and thank you in advance for the help.

I'm a first time grower and I am having an issue with my white widow auto.

Plant seems to be doing pretty well and was looking good for the first few weeks of flowering. Then, I started to get a lot or yellow/brown spots. It started on random lower leaves, and now seems to be concentrated around the main cola mostly.

I've been ph ing my water and used autoflower organic soil amendment. Directions said no notes, just water so that's what I've been doing.

The plants are a little close to the light since I'm in a 2×2×4 tent. I don't know if its over watering, light burn, nutrient issues or something else.

Any ideas based on the pics?

Thanks.

you kind of answered your own question without knowing it. If the problem starts at the bottom of the plant and moves up it is likely lacking nutrients. I think autos are using more nutrients and the strains continue to be developed.

Strange thing is the lower leaves are fine now. There were a few random yellow with brown spots, but now the issues is concentrated near the main cola and other parts of the plant seen fine.

Does that still sound like a nutrient issue?

How far away do you have the light and what is the brand and model of the light?
It is hard to tell what the issue is in the Burple light.

I have a 600 watt bloomspect LED with the dimmer turned all the way down. The plants are getting kind of close to the light since my tent is only 4 feet tall. They're maybe a few inches away.

Also betting very low humidity

My RH has been somewhere between 55-65. At least according to the sensors I have.

not to be difficult but you have a 600w bloowspect LED. It is specified to draw 132 watts from the wall. It might be light burn. Please post pics in regular light to confirm.

Well I shit the bed on that one didn't i. Temps? I think @Anthem is right about the light burn even at that lower wattage

One more Burple (is that a real word? It should be) pic, and a couple with more natural light.

Also, im sure you can tell I did not train or trim (until some recent trimming) at all figuring that will come on my next try once I have the environmental stuff figured out.

It looks to be light burn. You can also see how the leaves are starting to taco. That is the plants way of telling you it is getting too much light.
Be happy you have gotten this far on your first grow. A lot of folks never get to even smoke their first grow. Live and Learn. Oh and maybe a bigger tent. Gorilla is the gold standard. Theirs come with an extension so you can get a full 7'11 out of them.
