Avocado problems

Hi all - the folks in the veggie forum said this is where the avocado experts hang out so here I am with my newbie Avocado question ;)

We have grown this avocado from a seed (I know it won't taste the same, etc but it's a fun project to see it grow) It's maybe two years old, a single stem, and about 3 1/2 feet tall.

It's had brown edges on the leaves for a while due to salt burn according to an arborist who came to the house. But are the brown spots salt burn as well? I've googled but so far it's been inconclusive. Anyone know?

It's in a pot - I just repotted from a 10" to a 12" pot, with palm/citrus/succulent potting mix.

I flushed it with 4 gallons of water or so. More flushing? Fertilizer? I haven't fertilized it yet. Would fish emulsion be a good Nitrogen source for it?

Any help is much appreciated!!!!

slow...you may have a couple of problems. Firstly, when growing in containers there are some very important factors. 1. use a free draining potting mix (no moisture control stuff to create muck. 2. Make sure the container is large enough. 3. Watering regularly is critical. Also, persea mites can cause tan/silverfish spotting on the underside of leaves. They usually run along the vein line. You definitely have the soil moisture/watering issue.

Thanks fireduck - yes, it was in a smaller container before and would dry out all the time (bad bad mama) but I think the bigger container is helping, and I did use cactus/palm/citrus potting mix which is supposed to drain well.

However, the very tips of the newer leaves are still brown. The soil feels cool and moist under the mulch....hmmm...
I potted it up from a 12 to a 14 or so - my understanding is you should usually pot up gradually to larger sizes rather than going to a giant pot right away. I know avocado trees get huge....

the brown edges on those leaves will never re-green. No bigee. Keep it fed with low-dose fertilizer...and don't let it get root-bound.
