Hi . does anybody know if this color of stems is normal? is it strain related or some kind of def / tox ? its a random seed from my place and its a photo that i let grow in order to experiment with various technics like topping and supercropping
Also the start of the leaves has this weird color

I could be wrong but I think I read that whenever that occurs it's because the temp is to cold.
i think thats not it . i live in a greek island . the weather is too hot so im using big shade cloths . offcourse in the night sometimes the temps are dropping and there is huge humidity but i dont think is that much . day temp is 32-35C and night maybe 10-15C . all other plants are fine. do you think this might be causing it? or could it be just this feno?
@E_heroi There are several reasons that purple stems occur:
Genetics
Giving too cold of water
Too cold temperature. You mention 10-15C night temp; anything below 20C could cause purple stems
Some say phosphorous deficiency causes it but I personally haven't found a credible source that says that.
