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!

Can I fix this? Kinda looks bad.
I think effed up... Not exactly sure how or how bad it is. I haven't fed in a bit and looked like a nitrogen def starting, so I fed half strength, and 48hrs later I have this. Can I fix it? I did fish water this morning. Calcium def?

The lower leaves of some plants are yellow, then die. I'm very light with nutrients, there is no bugs into the grow room, what can it be ? pH between 6 and 7, lower it with few drops of lemon juice but bought a 3aciddown bottle. And are the buds supposed to be that big already ?

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.

Another round of Name That Deficiency
5 weeks into flower and this plant seems to be the problem child but she’s also the one showing the most growth. PH is 6 on her, was originally 6.2 but was having a manganese deficiency so went down to 6.0. Gave 3/4 of recommended nutrients in last feeding. Not sure what to do.

Yellowing leafs.
Hello guys, my plant is now on the final weeks of flowering, buds are getting bigger and the leafs are getting yellow pretty fast. It's this last thing that scares me a little, I know it's completely normal due to flowering but I wanted to ear your thoughts about it. Thank you 😊

Is this nute or sun burn? What should I do to save my babies ?
I upped the nutrients to week 2 of veg state (biobizz) and put the light to 50% intensity. I put the light at 6 inches above recommended height (which is recommended on the Mars Hydro website for beginners). . IS THIS NUTE BURN OR LIGHT BURN?

Yellowing leaves on bottom of plant, end of stretch to start of flower. Am i seeing a deficiency?
Hi GD, Im in week five and i started to notice some bottom leaves on my girls slowly turning yellow. Could this be due to them barely recieving any light? or starting defeciency? I am on the feed schedule in the pic, and watering with a ph of 6-6.3 (every 1-3 days, when dry)

Deficiency or lockout
Is this a simple N deficiency or a lockout? I gave her more N last feeding but nothing seems to have changed. still stunted and still bottom yellow leaves. Should I feed her a micro/bloom mix or flush her??! Her soil ph seems to be correct and ppm so idk if its a build up of salt
