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!

Nutrient deficiency? Or just getting ready for harvest? Sister plant is very green (different strain, strawBerry cheesecake, last pic)
Plant is Raspberry Kush, I’m assuming it’s because she is close to harvest and it’s sucking all the nutrients out. Also, looking up other raspberry kush diaries i’ve noticed they tend to end up pretty yellow. Was fed bloom nutes yesterday but noticed lots of yellowing today.

Seedlings yellow and showing spots
Picture of just the leaf is 11 days old. Thought maybe I was over watering it and I've only been watered it twice in a week about a cup each. spots are on it now. Temps have been mid 70s and humidty mid 60s. Picture of the smaller plant is about a week younger than other plant.

Yellowing leaves with brown spots close to harvest
Is this yellowing normal as I approach harvest or is this something I should have been taking care of? If it is how could I?

Should I cut off the affected leaves ?
Hi growers, It's been a week and a half since I had a big ph change and the SZ has been hurting. Now it's around 6. Should I cut off the affected leaves to make space)? The ones below are growing normally now :) The green gelato looks really healthy btw ! Thanks u Peace

Yellow spots on bottom leaves.
Starting to notice big brown/yellow spots on the bottom leaves only. Plants look healthy at the top but not happy(not praying and look droopy). I water every 3/4 days so it’s not a matter of being locked and Calmag is also used. Can’t figure out what the problem is here.

Heavy fast yellowing
I flushed my plant because of too high ppm reading from run off and now she seems to be going all yellow. Is this normal for this stage of the grow (all trichomes still white and small buds) or is this a definite nutrients deficiency during flowering?

Yellow Cotyledons?
NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?

Been flushing for the past week, the larger fan leaves are starting too turn yellow faster than I had anticipated but trich's haven't started turning amber yet. All the other sign's point towards her being about a week away from the chop but I'm a bit worried that I flushed early

What are these yellow/brown dots and how can I prevent more from developing?
Yellow/brown dots appeared midway through week 4 of flowering. More prominent on upper fan leaves. Gave it nutrient tea (flower nute/worm casting/CalMag) so hopefully that will help. Can’t test pH so difficult to tell if it’s lockout. Added new 600W light this week too.
