foliar feeding

I got them as seedlings last winter. It's just the bottom leaves that are getting old, turning yellow. Do you think it's not the light issue?

No I wouldn't say it has anything to do with light if the upper leaves are still green. Most likely the plants are just losing their lower leaves naturally to allocate resources to the growing parts. As long as the new leaves are maturing larger than the older leaves, the plants should be fine.
