I am not so sure you are getting nut burn. What kind of soil and nutrients are you useing? What is the PH of the nutrient water you feed them? What is the PH of the soil. Do you have good drainage? The one leaf that is just a light yellow color, looks like Nitrogen def. But you are in flowering, this happens a lot of times. The one picture with the yellowing leaf with the redish colored center, Is it crispy or soft where it is red?

They look hungry to me. Since you are still only 4 weeks into flowering, you could hit them with a bit of veg nutes, which has a higher proportion of N and as LDB said, the yellowing is N def. The leaf that is very yellow will probably fall off if you touch it. This is a natural thing. The plant has finished with that leaf so is stripping the nutes from it before it lets it go. Up your nutes also because I dont see any nute burn either. JMO W

that is not a burn. its a deficiency. water then with a good 900 ppm at 6.2, then go sock whoever gave you the other advice in the mouth.

I agree with those guys, they look underfed, not overfed, if anything. Actually, they look pretty healthy, going through the normal yellowing, that slowly happens throughout flowering. It may be a tad early, but no real emergency. I'd just step up feeding a little, and keep on truckin.lol Seriously man, they look pretty good, from what I can see in the pics. Leaves are going to start to yellow and drop off, starting at the lower end, that's inevitable, whether it be from low light, old age, mild underfeeding, etc....

I voting under fed cause of the flat leaves lack of pertyness. Fourth week in flowering you should be able to give it a full dose. At least 1000-1400 ppm with a meter~

You never did answer the question of what kind of soil are you using. You just said you water everyday. I hope you are in CoCo and not soil. Watering everyday in soil is way to often. You should be watering every 3-5 days. Soak them down good, until you have plenty of run off, then wait for the pot to get light. I think you are giving them to little water to often. This is not allowing the nutrients and fresh oxygen to get to the bottom area of the pot.

"Piss yellow" on the ph drops indicates a ph of 6.0, probably not what soil guys want to see ;) I shoot for "piss Yellow", but I am hydro!

^Excellent canopy management, bro. Looking good. :weed:



Also, I agree, he should be looking for something in the blue-green range, if I remember correctly.(I haven't used my drop tester, in quite awhile)

Thx bro, just wanted to show him that mine are thriving at "piss yellow" and I'm in Hydro, he is in soil though ;)
