Phosphorous and potassium deficiency.
A P/K booster will fix this.
The damaged leaves will not recover, but it will prevent this from getting any worse.
Both these nutrients are needed in larger quantities during flowering.

One of my plants fans are yellowing, spotting, pretty badly. The medium PH is 6.5, same as my other plants, but she just doesn’t seem to be liking it. I’m using nutrients, but not heavily. About a quarter teaspoon per gallon of the flora trio. It’s the mid fans not bottom or new.Week 6

What’s going on here?What’s going on with this one bud on Cotton Candy Kush plant? It has some leaves dying. No damage to the stem & only bud looking this way. It’s on day 50 of flower and has been getting lighter leaves overall this week. It’s supposed to flower 50-60 days, according to the breeder.Week 11

Are they still looking overwatered?How are my babies looking? Watering now every 24h (0,5l) and I raised the pots so they no longer stand in the runoff (doh!). The calmag also arrived today so hopefully that will help my Green Gelato with the yellowing 🙌Week 6

Yellow leaves since 1 weekHello my friends,
More and more yellow leaves since 1 week.
I need to be worry?
I think it's not a problem of ph because my other plant look healthy.
Maybe too much water?
I just give her 2 x 0.6 liter per week and fertilizer only 1 times per week.
Senescence?
Thanks for helpWeek 11
