It has been repotted for a while it is indoors getting filtered afternoon sun leaves feel very limp.

is saturn frank?? ...

Yes

They're famously hard to grow in pots started from seed indoors. You should also know that avocado grown from seeds you planted from an avocado bought in the store is not going to produce the same kind of fruit. I have read that even those who are successful in getting their avocado to flower and fruit find that the fruits are often hard and inedible. If you are looking at this as an interesting houseplant, there are easier and prettier options. If you are looking at this as a food source, that's likely not going to turn out as you hope. Other things I've read about avocado: they do need a lot of light, so filtered afternoon sunlight is definitely not providing the light needs for your plant. But as another poster pointed out, throwing it outside into direct sunlight at this point would also probably shock it, and could cause droopy or burned leaves. If you are going to keep it, putting it outside in direct light would ultimately be the best for it, but you would want to slowly get it used to that through a hardening off process-- put it outside in filtered light first, then slowly increase the time so it gets used to the outdoor light intensity and wind. Then slowly increase the time in direct sun by an hour a day. Another thing is that they HATE being repotted- their roots are very sensitive and the plant will go into shock for a while after being moved up to a bigger pot. As far as watering and fertilization needs, I believe it's the same as citrus trees-- so a quick-draining soil medium, don't let it dry out but it also hates wet feet, and once it is healthy and growing it does like some citrus fertilizer diluted at half strength about 1x week. Final piece of advice I read, though it's probably too late on your plant for this one-- someone told me that after the avocado has sprouted initially and has 2 true leaves, to pinch it completely off just above the soil. I did that on mine and for a while thought it was a goner. But it did sprout back, and the new stem & leaves were a lot stronger and able to withstand wind and sun outdoors. Good luck, you picked a hard plant to grow!
