prabhisetty,
I have read through your posts from the beginning. It would be a good idea to post your general location (not exact) so that we can give a more accurate answer in relation to your growing conditions available.
When you posted your soil mix and said "Canadian Sand", it got me wondering exactly what the sand is like. Most Sands used should be a coarse sand, such as River Sand. A fine grained sand mixed with Coco Peat could be detrimental to the root health.
It looks that you have had these for 1-2 months?
Is it just the seedlings in single planter or including the older trees in separate pots.
Nice trees.
Rick
