1. Fill out troubleshooting form....include height of plant above the soil for me.

2. Flush now....what size is that pot? How long in that pot?

3. I cannot see everything I need to see, but I think you have issues with root rot or over watering, possibly need repotting. You should see this type of yellowing in lockouts....note how it is greener at the veins, not a complete yellowing of the sun leaves.

Frankly without knowing lighting, age, pot size, potting mix type, just hard to tell.

Rusty, I think you might be better at this one than me.....once the info is posted.
