Another yellow leaf question

[Gee]

I have a few leaves a day yellowing at the bottom of my blue dream plant. The oldest leaves. I assume this is the plants way of “self defoliating” leaves that have no more use to them. The rest of the plant is doing fantastic! Normal right??

Hiya Gee I'd guess most likely. How old are they?

Had the since I got them as clones in mid May. 3 months. It’s only the bottom leaves yellowing one at a time. Everything else is green. I just took this

Looking healthy, I'd guess you're just fine, normal old used leaf loss. Nice plant! Cheers mate!
