If that’s just the bottoms, I wouldn’t worry—- looks like there might be soil on the underside of the leaves? Flip them and make sure you don’t have spider mites.

YELLOWING IN DWC!
Recently a friend transplanted his Northern lights auto into a DWC set up, since then the plant has suffered severe yellowing and stunted growth. His nute feeds are optimal just as they were in his coco format and his PPM keeps decreasing. Any ideas?

Anybody got any idea with what's going on with these 2? The 2 larger plants are showing the signs of some stress on the fan leaves. Oddly enough the runt of the 3 is not showing these signs. Has anyone seen this before or can help me identify it?

Your opinion?
Today flushing the wedding cake i was thinking that the problem was an excess of nutrients, but instead water was quite clean, around 1100ppm at the first drain, after several flushes water is now on 600ppm. I also raised the lights.. I still do not understand 🤔

Yellowing to slight grey leaves
What's the cause of the older yellowing leaves with some grey and the slow spread to the newer growth? I'm between pH problems and or deficiency but not too sure.

Ongoing brown and yellow patches forming in week 6 of flower
I've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)

Too close to light? Nute deficiency?
Yellow leave with brown spots, what is going on? Showed up really in the last 2 days. It got a half strength dose of big bloom every other watering, the light was pretty close about 6-8 inches away. I didn’t check on it for 3 days so it grew a bit and was super dry.

Should i worry?
Should i worry? Other growers said this is most likely a potassium shortage yesterday so I started feeding her a little more but if I compare todays pics to the pics of a few days ago I'm kinda shocked. You'll see which are the pics of today

New leaves have yellow and/or curled tips (-> nutrient burn?), and many leaves have their edges curled up (-> root problem?). The pot that I'm using is fairly small and only has a small hole for drainage. Can this develop into a serious problem?

Yellowing/browning near veins of leaves during 4th week of flowering?
This is my 4th week of flowering. Should I be concerned about the yellowing/browning near the veins of the leaves. Some small ones are dropping on their own as well.
