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

Leaf problem and purple stems
Hi, I have a problem with my auto. I have purple stems and problems with the leaves. The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem. Is it a nitrogen deficiency ? Thank you for the answer

Purple stems on some seedlings?
Why would the plants on that edge of the tray have purple stems? Nutrient deficiency? I noticed the one I checked with a purple stem had more roots showing from the rockwool cube than any others... think they're trying harder to get to the juice cause they got shorted?

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.

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.

Purple petioles and cupping down
So, after watering with root+ 1.3ml/gal and amino extreme 1.4ml/gal and putting in a light that is double the wattage from the one prior it seems they got light/heat stressed. The purple petiole color could be phenotypic as it's striated in the stem too but I'm not 100%. Help?!

Unusual new growth and clawing. Possible toxicity or def.
Anyone know what this could be? I'm guessing N excess but I'm not sure.
