Stems purple that lead to new fan leaves

[BeginnersLuck]

Hi, I am fighting some issues -

https://www.rollitup.org/dwc-bubbleponics/308206-nube-here-help-appreciated.html

And have noticed that on some of my "new and healthy" growth the junction where the stem meets the fan leave is purpleish.. In addition so is the top half of that stem. Is this a concern of mine or normal?

Thanks,

Beginner

Purple stems often indicate too cold, what are your temps lights on and off? ideally they want to be 20-21C off and 24-26C on.

John thanks for your feedback.

Night time 64 F (17.8 c) and 50% RH
Day time 79 F (26.1 c) and 40% RH...

This is only on my new growth and I am flushing the last 2 days after overfeeding the girls...

I only see it on 3-5 of 20 plants.

Thanks again much graciass

64f is a bit cold, try and up it to 68-71F. What medium are u using?

I am using the 6 inch extreme rockwool cubes using top feed right now. On monday I plan on transplanting them into a Cap Ebb and Grow system and using the ebb/flow - flood/drain method....

Thanks again

over feeding.

Purple stems are no big deal. Over feeding would show in the leaves before the stems. Nute burn on the edges. The temps could play a major factor as said earlier or could be genetics but as you said the new growth looks healthy. Some indicas show alot of purple later in growth.

Ahh I cant turn up my heater any more its at its max.. Its still getting in the teens here at night. I have been leaving my room open with a box fan in the entrance to move air til I get my 6 inch can fan intake and 4 inch carbon scrubber in 8 days... I can shut the room at night, I have a timer on the fan and that shuts off at about 1 am and back on at 5 the same times the heater kicks on and off. I will have a look and see if its only on the Bubbilicous like I think...

Thanks,

This one come's around a couple of time's a month and i always say the same thing if the plant looks good then carry on doing what your doing.Some grower's will say it is a plants way of telling you that it needs more feed but i have personaly had this with the feed on full.Others say that it is in the genetics of some cannbis strains either could be the right answer but if your plants growing and looks good then carry on doing what your doing...............tyke...................................
