Have a lil issue going on at day 58 from sprout. Roughly 4 weeks into flower, growing in FF happy frog, fabric 3 gal bag, using FF trio for nutrients at 1/2 strength. PH at 6.5 for every watering and feeding. I only feed twice a week. Using a electric sky VS300v2 as high as it will go in my 5x3 tent. Have the dimmer knob around 3/4. These spots on the leaves don't seem to have any pattern as to where they show up on the plant, some were at top, some at the bottom, as well as in between. I cut these off last night and that many more have showed up today. Any idea what this is and how to go about treating it? Thank's a bunch.
Also, the plant is a northern lights auto from growers choice.
Temperature stays between 77-79 during the day and 66-69 at night. Humidity fluctuates between 44-49%

pH is fine, PPM is ok. Although, often times I will go as high as 1600 PPM when in flowering. So they may just be hungry. The other things you mention (temp, humidity, etc) are fine. What genetics are they?
No light leaks or schedule changes, it's an autoflower as well. The soil runoff is 6.2 and the runoff ppm is 1125.
The plant looks like it re-vegged at one point? Did you have any light leak issues or issues changing light cycle? Also can you tell us what is the pH and PPM of the soil runoff?
