Purple leaf ?

[Lofty]

Hey all !

Recently i sowed my seeds and they shot and one of them came up with the two embronic leaves out and the first set of serated leaves are purple ? whats the go ? do i need more nutrients or is there to much in the soil ?

Probably just a bit cold, preventing full nute uptake and the plant is responding by producing anthrocyanin as a sort of sunscreen from the early morning sun...

 

I'd love to see this tho, any chance of a pic? Let the seedling grow if all else seems okay like soil and the others in similar circumstances are doing ok... If it passes, it passes, just look after it normally and it should do okay, I think. Unless you've got some amazing mutant permanently purple plant...

 

What kind of soil/setup are they in?

[Guest Wilderbud]

Seeds contain enough nutrient to grow a small seedling if they are mature enough. If you do feed seeds or seedlings do it only once per week and make it 1/4 strength.

its not from more anthocyanin its from less chlorophyll which lets the anthocyanin show through.

how do you guys know so much about plants?

[Lofty]

Yeah the soil is just a decent potting mix. hopefully it will correct its self !

Hmmmmm a purple plant could be quite funny !

No pic man sozz ! haven't got a new digital camera yet ! when i get my new one i'll take a few for ya !

I think we might've read too much. Plants that show purple generally have the same level of anthocyanin as all cannabis, its the chlorophyll levels that change.

 

Thats totally book based knowledge, in my own opinion I reckon what luke said seems more right, because purple dope always seems very harsh and peppery, which could mean anthocyanin tastes like shit, but I'll take scientist advice over my own.

 

Lofty I've never seen that happen to a cannabis seedling cos it just dont get that cold where i sprout my seeds, but I have had it happen to tomatoe seedlings which have become totally stunted. But usually they will have purple/grey cotyledon (seed leaves) then never grow further leaves.

There is also the possibility that it is a different strain from the others, are the seeds from deals Lofty?

 

Other than that I would be inclined to look for a draught or a source of cold air (intake vent?) that affects that area of the grow room.

[Lofty]

Yeah that was my first thourght. Yeah i just got the seeds off a mate so who knows what was in there! It's been grown outside, only one out of about 30 seeds has turned out like that.
