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

New red tint on top of branches caused by night of low humidity or other stress?
This morning I noticed some branches on my young plants had turned reddish on top. Last night the humidifier ran out of water and RH dropped to 40% overnight. Could this just be a stress reaction to that low RH, or sign of a deeper issue?

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 �

Phosphorus? Potassium? CalMag? What is going on here?
So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think it’s a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!

Stem on plant appears to be narrow at the bottom growing beefier up higher
The stem on this plant appears to be narrow at the bottom growing beefier up higher. Any ideas on strengthening it up or will this hurt me further along?😲 I think this plant got knocked over once so perhaps thats it, just hope it doesn't choke the plant further along. Ideas?

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.
