Bottom leaves yellowing - normal or issue?

I’ve been doing a fair amount of pruning, and the top seems fine.

It’s normal for a cannabis plant to shed its lower leaves as the plant matures. The one suggestion that I have is to provide your plant with more light.

one of the two are almost 1" from the lights - what I can do is increase the light output, which I’ll do.

The best LEDs for growing cannabis are manufactured with Samsung LM301 series diodes.

Horticulture Lighting Group, Spider Farmer, and Mars Hydro are all good options.

Cannabis will struggle in flowering with a 100 watt light. I suggest reading this thread about lighting.

Start using DLI

Daily Light Interval (DLI) is a quick and efficient way to calculate how much light our plants are receiving within a 24hr period, allowing for easy light adjustments. DLI will help you and the community to better understand your lighting in a more universal term, leading to clearer communication of what the true light value is. Almost all smartphones have the ability to use an app (we will get to this don’t jump the gun) in order to calculate DLI, and if that is not an option a cheap LUX meter…

Thank you…

The “Start Using DLI” link was very informative and adjustments have been made - thank you.

Seems like you are on the right track. Happy growing.
