HELP! Gorilla glue's leaf turn yellow

[wiiniez]

I am from Thailand, so my English is not good. My gorilla glue is 46 days(total), and about 5 days ago, it turns yellows with some black or purple spot on the leafs. My PH level is 6.8, Temp is 24-28c, and humidity is 50-65%. I am using Advance Nutrient as my fertilizer. What happen with my cannabis plants???

Hey there wiiniez, is she an auto or photo? It almost looks like it's starting to finish up. How do the trichomes look?

 

[wiiniez]

She is Auto. I think the trichomes is still not ready.

Goodmorning from Oregon. Those are cloudy looking trichomes to me. If it were mine I would not give anymore nutes because I think it's got lock out. Stop and flush with PH water allow it to dry out before watering again. How close are your lights? Remove those dying leaves only, It's about finished.

I really appreciate it. My light is about 30cm from the top leaf. Do I still have to use Flawless from Advance Nutrient to do the flush or just using water only. Thank you!

I don't use that product, maybe somebody else on this site could help with that question. And I don't know about your light strength if it's penetrating mid to lower part of your plant. They don't drink as much later in flower. It's good to allow the medium to dry between watering.

Do I have to cut the leaf out?
