No debes preocuparte para nada, las lineas moradas pueden salir hasta por un leve estrés en la planta, si no ves otro síntoma debes sentirte feliz por tu trabajo! Buenos humos! 👌

Nein, kannst beruhigt sein. Ist entweder Genetik, oder Lichtstress.

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?!

Is it nutrients? Light?
What can this be? The stem is red, and I thought it could be over lighting (I had 2 LEDs of 200 W each), so I removed one of it. But now I am also wondering that it can be nutrients, no? If so, how can I solve it? Let me know what you think. It's an autoflower - 7 weeek.

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.

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

Spider mites?
My partner just cut some clones off of a pre-flowering plant & put them in a root rain spray cloned. Been 2 days since he cut the clones. No roots yet but he’s wondering if he has spider mites & if so what he should do. Do you all notice anything wrong?

Purple Stems
Hi, Phenos like Sideral do not normally tend to color at the end of flowering (unlike Wedding Cake). However, the stems are already quite purple! I know low temperatures cause stress causing staining, but that much ? UV's and IR's of led light? An excess of something? Thx a Lot �

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.

Week 7 Flower - No Color Loss?
What’s up Gromies! I have see almost always in late flower phase around weeks 5-6, leaves will begin to discolor as thebuds suck up all that yummy nutrition. This AK-47 XTRM from AMS is retaining its color and tomorrow is the start of week 7 of 8. LMK your thoughts!🧐
