okae so shes about a week old and 3cm tall and the new shoots are slightly purple wats happening? shes bag seed and outside i was curious to if it was from some sort of bug???
phosphorus deficiency causes purple leaves, this happens a lot with cold weather.
if you see redness on stems, thats totally different, usually nitrogen deficiency.
no way is it a phosphorus deficiency she gets a weak dosage of phostrogen high in phosphorus and nitrogen and yes it is cold in the morning i found little driplets of warter COLD water all over her little we leaves
