Yellowing of the lower leaves during flowering is quite normal/common, but either add or up your P/K booster to help your plant, she will be hungry for phosphorous (P) and especially potassium (K) during flowering.

The damaged leaves won't recover, but it will prevent the other leaves from suffering the same fate.

Yellow leaves since 1 week
Hello 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 help

The leaves started to turn yellow from the inside out. I don't know if it's a disability or an overdose. I'm using Biobizz. Someone solve? Is it in flowering with about 5 weeks to harvest, is it worth stirring or better leaving it like this?

Slow growth yellow leaf edges what to do?
Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.

Why are my plants leaves so bright green/yellow?
Wondering if anyone knows why the plants might be looking as light green as they are? We are running a purely organic grow and have not added nutrients beyond the super soil mixture. Wondering if anyone has any tips or suggestions, thanks!

4 days without water
I had to leave for 4 days this past week. Gave both plants H2O before leaving but I came back and one of my plants has some ugly yellow and brown leaves. Do I need to do anything to correct this or just get back to my routine feedings?

Deficiency?
I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight
