Well its just 10days old so it can't be any nutrients deficiency
Plant clinic said it must be because of ec and my coco is cheap and salty
So he advised me to transplant it to a little bit biger pot of peat-perlite no coco anymore that cheap coco is salty and useless
So im gonna get rid of that damn coco
And move them to peat
I'll show you the results later
And tnx for quotes and advises
I don't know how growing in Coco works or if it has nutes like a soil promix does that it can feed from . Does it feed the seedling with nutes for the first while like most promix soils do, or are you feeding it? If it's not cold, and its not genetics, all I can think of is Phosphorus problem from the look of it. Someone can most definitely correct me if I'm way off base here but like I said, I just went through this because my soil has no more nutrients left. I looked all over the place as to why my stems which were green, were now turning pink, red then to purple in a matter of 2 days.
Signs for me were stems turning pinkish ---> Drooping leaves / stems -----> Stems turinng reddish ------ (Watered - no nutes) ------> slight leaf uptick from drooping ------> Stems turning purple, fan leaves blotching and leaves drooping again after short recovery. -------> (Watered - Full serving of nutes) ------->Fan leaves yellow with weird blotch discoloration / Plant recovering / No more drooping / Non affected leaves and new growth ok again. Today shes happy.
Again, just trying to help. I'm sharing what seems pretty similar except for age of plant. My phos problem also stunted my plant for about half a week.
Although I hear its common for reddish stems the first couple days/weeks or by genetics. My understanding is your is turning purple from green....
PS - If Coco doesn't have nutes like promix soil etc .. then I wouldn't have the slightest clue as to how much you would have to put food in your water for something so small.
