Purple Stems

Mattustonstarted grow question 5y ago

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 �

Nothing to worry about man. You're leaves look very healthy. Some strains just have purple/brown stems. Its all genetics. Purple weed will more likely have purple stems.

Stems becoming red. I didn't use any nutrients yet. Should I add a little bit of them to water? Water pH is about 6.5. Do the leaves look ok?Looks like stems becoming a little bit red.. I've checked other diaries with this strain and didn't found anything like that. Before transplantation I have completely flushed my soil about 2 times because I found a lot of springtails in. Hope I didn't got rid of all nutrients..

Leaf color What you think about it? Is she getting too much? I’m not giving her too much in my opinion. Her stems are purple and the leaves are yellowing a bit. Watering always with ph 6,3-6,5 growing in soil. I have a diary from her too. She’s like 47days old. Happy growing!

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?
