Leaf spots!
yatzistarted grow question 4 years ago
Leaf septoria or nute deficiency? Don't have ability to monitor pH or ppm. Do I cut the affected leaves off or any other home brew solution? 3 different plants in the photos.

The yellowing looks like you may need to start feeding. The spots look like you may have gotten water on leaves while light was on. I wouldn't cut them off until yellow.

Imgur link with closer up photos, not convinced its not a fungal issue just yet. (https://imgur.com/a/b1ysPpw) Picture 4 does kinda look just normally burnt, but picture 5 with the pretty convincing circle is making me think it could be septoria.

Looks like wind burn to me. Doesn't look serious. Cut that yellow one at the bottom. Weed is resilient

I was using "Maggie's farm 3 in 1 spray" in an attempt to keep sawflies away. Has some oils in it so you could be right. I wanted to be sure it wasn't any type of fungus. I'll wait for maybe 1 or two other opinions but thanks hempkid!

P. S. I noticed the yellow on the 1st plant and already threw it a little more 4-4-4 a day or two ago.
