I have a bunch of plants in pots (left over from a purchase that I had to resale). They are rabbiteye plants, approximately 2 year old plants. Tifblue, Brightwell, Alapaha and Powderblue) Most of them are fruiting. There are numerous plants (if you recall the sucker plants I got unknowingly, that were questionable) Well some of these have leafed out but have never shown any sign of flowering /fruiting.

question 1: the leaves on many if not all of these have speckled reddish looking spots/flecks. Since this is how most of them appear, it almost seems "normal" but please let me know if it could be something else.

question 2: the plants (sucker roots) that have leafed out, but have not had any flowers, what would be the reason for this and will they ever produce fruit?

These plants will remain in pots until next year and I'm not worried about the content of the containers soil wise. but I'm not 100% sure about fertilizing and whether liquid vs time released would be best for potted plants?

1. When to fertilize

2. How often
