Hello all. Below I'm attaching some photos of my two year old fruit punch mango tree,for some reason the new growth is not turning totally green,and the tips seem to go brown on me,so question is,I'm i over fertilizing? Or is this something i can correct by applying some type of spray to the leaves?
Thanks all.

What type of soil do you have?  pH?  What types of fertilizers have you used?

It looks like Iron or possibly Manganese deficiency since itís affecting the younger growth.

Could also be deficiencies of Magnesium or Sulfur.

Is my VP stunted for some reason? Itís been in ground for 6 months and havenít grown at all except for showing some green buds. It was a leggy tree from the beginning. Is there something I can do  to bring it out of dormancy?

Did you cut off the circling roots when you removed your VP from its container?  If not, your tree is probably root-bound.

It is also desireable for a tree to concentrate its energies on root system enhancement, before increasing the canopy.

I haven't cut the circling roots during planting. Should I dig around the VP to disturb the roots? Or, is it too late for the tree? Thanks.

If you remember the pot size, you can slice down deep with a long sharpened spade, with one edge of the spade toward the trunk, at four points.

Good idea, I just drove a spade in all 4 corners of the VP. It was from a 5 gallon. Thanks for your advice.

In case of circling Roots, Can you describe how we should proceed before planting? Uncircle them and make the cuts? What about the tap Root? Should we prune it if it is circling? Thanks you in advance

I use needle-nosed clippers.  I cut all roots of any size that were touching the pot, bottom and sides. 

I don't dig more than 1/4 inch into the root-ball--- usually 1/8--- unless a plant is terribly potbound with already fat roots;  then maybe one has to dig 2 inches into the sides to cut one-inch thick circling roots.  A terribly root-bound tree, after root-pruning, should be re-potted, placed under 70-85% shade, staked and the top of the plant should be bagged with a clear plastic bag, for about two months.

Can someone tell me what is going on with this Ataulfo seedling? It grew these long curving leaves and weird clumps of buds last year and hasnít done anything since.

My picture didn’t load last time, trying again.

*edit - didn’t load this time either, trying to figure out what I’m doing wrong.
