Plant needs more potassium. A P/K booster will help, or increase the amount if you are already using some.

Most likely turning yellow because it's getting to the end of its life cycle.... I don't see anything to worry about except the length of time you're going to be in trim jail in the near future! Good luck!

Calcium deficiency or overfed?
Hi. This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress. Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain. Thanks!

Leaves are turning yellow and dieing. Looks just like nitrogen deficiency but my PH has been running high. Could someone look through my latest entry?
Interior lower and middle leaves turn yellow and die. Seems like nitrogen def. PH measured w soil meter read 7.3, 7.4, 7.5 at the highest. Plants are huge. Have the just used up soil nutes and I need to increase feeding or is it PH and how to fix. Water pH is good. Plz see diary

Deficiency or Genetics
Would you guys guess the yellowing on these leaves is more natural coloration from genetics or do you guys see something more? Plant is definately small but seems to be healthy and buds keep growing.

Yellowing copper leaves late flower
Harvest is coming up soon and I have noticed some of my leaves mostly the bottom but some on top also have started to turn yellow with brown/copper spots. I believe it is cal mag deficiency, will this mess with my yield or quality of the bud?

Did I go too light with the nutrients this time around? Yellow leaves and fading pretty quick. A good dose of nutes next watering?
My plant has about 3-4 weeks left, I have always had nute burn so I went what I think was way too light w the nutes this time. Is this a nitrogen deficiency along w calmag deficiency? I'm in week 3 of flower, should I give a good dose of nutes next watering? Advice appreciated.

Yellowing leaves.
Is this a Nitrogen, Magnesium or Iron deficiency? I tried looking at pictures online, but they all look very similar. Or because of me under watering? I know I have not been giving them enough water. Growing outside in soil. Gave them nutrients 2nd of January.

Natural or Problem?
Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

Is this yellowing normal? Probably because of LST?
I am growing my plant with LST and some of the lower fan leaves have been moved down in the shadow. Is this the reason why those leaves are getting yellow and dry? All the rest of the leaves look very green and healthy by the way.
