Best you can do is get a good phone and download a LUX meter. Convert the reading into ppfd using Google, then find a chart of ppfd needed for cannabis either week by week or by phase.
This will give you a good idea, but you will need to adjust according to what the plant is telling you.

Kind is prob your best bet. Hell if the temps are fine throw that and the other led in. 🤘😤

Is this a sign of too much light?I’m noticing the leaves grow extremely close to each other, should I be concerned at this stage, should I pull the light higher back? This is day 3 of week 2, I’m feeding it full advanced nutrients line up for veg. And drying out for a day and a half between waterings
