This poor dwarf doesn't seem to be growing at all...I'm keeping her because I know that sometime she may take off growing but if things go like these in the next few weeks I'll discard her, I may plant her outside and she'll die because of the cold weather that is coming in autumm and winter. I'm sorry.
But hope is not gone yet, I'll keep her going some more time. I acknowledge that she comes from a old seed so she may have had trouble being born etc. so I'm having patience with her.
Btw the tips of the older leaves are yellowing but since new leaves don't show issues I won't change her fertigation regime yet.
