White Mulberry, black leaf tips

JMO

This is one of the first trees I have grown from a seedling and I am noticing these black tips on the leaves. It gets really good light in a south window and will be ready for its first trip outside this week. It get adequate water, not too much, but never dries out completely. The soil is Profile aquatic soil, grit, and pine bark in equal parts.

I have mostly stuck with scheff and ficus since I began about 6 months ago and this is my first decidous tree so I am learning.

Can anyone help me out with this one? There are two photos, one of each leaf that is showing this symptom.

Thanks,
Justin

The leaf tip burn as shown on your pictures is a physiological disease problem that is often difficult to diagnose the exact cause because of the many factors that can cause it. Moisture stress (usually too much), high soluble salts, fertilizer deficiencies, and fluoride toxicity are the most common causes.
More often, excess salt built up from fertilizing is the main cause because unused excess salts in the soil can damage plant root hairs, or prevent them from its proper absorption of water, which as a result aren't able to supply enough water to the leaves to offset the water lost especially during periods of rapid transpiration. This results in drying of leaf tips. This type of problem mostly occurs when it is dry and hot, often on newly transplanted trees.
Start by looking the watering practices, too much or too little. If you fertilize, back off the fertilizing and leach out the excess salts with water by carrying out a heavy drenching of your substrate.

Myrothecium Leaf Spot ? Cylindrosporium leaf spot ?0r just plan 0ld "black spot"?

I gotta tell you.Fungal and bacterial diseases used to be a real killer for me,literally.I tried all sorts of sprays,powders,tonics,and tinctures.The only thing that worked for me was moving to another part of town.

maybe because it has been kept inside the leaves are tender.

I would get it outside in dappled shade as soon as possible
