How much will I yield out of this Auto Blueberry - Outdoor?

[madatakesi]

The plant is 48 days old , was first growed indoor but for some private reason i had to move it outdoor while it's flowering but in my zone the sun is really bright and hot with a good air condition so the plant seems to like the weather and develop the buds like crazy . I want to ask how much should i expect this plant to yield ? And when should i harvest her ? And what is the burned spot at the tip of the leaves ??
The plant is about 30cm tall with one main cola . Growing in a 4liters pot so i guess that's why the plant is so small because it doesnt has so much place to develop the roots .

14 to 20g I'll guess. The sun should get you tight, fat buds.

At the moment it's raining , should the rain be a big issue for my plant ?
