From the looks of it, it looks like a leaf dying from not getting enough light which is completely normal. Hopefully, I answered your question and remember " Happy Growing".

Lower leaves turning pale/yellow/brown
For the past four weeks the lower fan leaves on my plant have been getting pale green then yellow/brown. the stems have turned purple and I have noticed the last week or so the tips of the leaves have been slowly turning brown. Should i worry at this stage of growth?

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks

Should I flush? (Overfeeding)
I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.
