Your plant leaves appear healthy. If just the stems are turning purple, most likely cause is from intense light. Nothing to worry about.

Help needed - harvest time?
Hi, I'm now in week 12 and I feel that after the flush my 2 vertigo stopped developing. They also have a lot of leaves with some mag issues. Not all the pistols are amber (70%). Also, the trichomes are not all cloudy. I'm not sure but I think I don't see changes anymore.

Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?
Is this a Mg or N deficiency or are these leaves naturally dying off? Showing on only one of two plants so far. Appears only on lowest fan leaves. F20, 7L pots BioBizz AllMix and nutes (1mL/L Grow and 2mL/L Bloom). Temp/RH are good. Can't measure pH. Local soft tap water 7-8pH.

Purple discoloration on the leaf stems... even though I pay close attention to always watering with a pH of 6.5, something is wrong with my plant... what could be the cause? A nutrient lockout seems to be the case...

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.
Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?

Why are the branches turning purple?
What is causing my plant stems to start to turn purple? They feel stiff and dry, could it be low humidity or am I not watering enough or to much? I water 1L/plant ever other day. PH 6.3-6.5. Should I be concerned?

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.
Older leaves have brown/red rusty spots and looks like dying tissue in between the veins. Burnt tips, and yellowing leaves. The soil was really dry and my PH meter was 0.4 too high. I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff. Runoff was PH: 6.1 EC: 0.8

The stems began to turn red
Guys, I need your help! The stems began to turn red. Yesterday it was less, but today it is more saturated and spreads to the veins of the leaves. Could it be a phosphorus deficiency, or am I worrying for nothing? And what is better to do in this case?

Purple stem
I read that purple stems can be due to many things... but I’m not sure what this could be - is it a nutrient issue? pH? “Tan”? Genetics?
