19 day old guava slushy by green Bodhi, 1st week of veg temp 82 degrees and humidity avg 50-55%. Just increased light intensity to 75% from 50%. Manual says to hang at 16 inches I currently have at 21 inches to be on safe side. Does this look like light stress? Should leaves be that light?
Help I think it may be light stress

Doesn't really appear to be light stress bro, I'm might as bold as to say 50 percent sounds like adquate enough lighting, you don't by any chance have a ppfd meter, if not can you tell me if you have and android based phone or apple because I know there is a free ppfd meter app called photone it's on the play store on android its not 100% spot on but it's not far off a real pprd meter tested it against my mates real ppfd meter it's only like 20 umols in the difference and it let's you select a meter for every type of light currently on the market today, also if you could get a humidifier in there ASAP or any other viable way of raising your humidity up to between 65-75 for optimal plant growth to thrive, best of luck bro this is all purely speculation but these little changes can be crucial to getting a fat yeald

For your stage in development right now I would be aiming for a ppfd of somewhere in between say 350 and 550, go for 550-650 mid to late veg 650-750, flipping to flower light schedual 750-850, 3rd week of flowering 850-950, swelling of buds till harvest 950-1100 beyond 1100 there's no point in going any higher unless your supplementing with added co2 then you can go a but higher but not really worth pushing to that level just keep your environment in check and you'll be good

Regarding color I would up your N a touch now not too much I presume by the fabric pot your just hand feeding and if so what strenght nutes are you using right now some go 1/4 or 1/2 strenght and all looks OK that will do them until they need to increase based on the plants current needs I can see a slight N deficiency, so give me a little more info on your current run and we have a good go at getting to the bottom of what's wrong cheers buddy

I think she looks good, new growth is typically going to start brighter green, that purple cow indicanja is good stuff

Is light stress even a thing? I've seen heat stress, but never anything I could identify as being caused by "too much light".

yes it is, it often it results in light bleached leaves which affects the plants ability to photosynthesize properly among other issues

makes sense, I have seen pics of light bleaching now that you mention it. When I google image "light stress", it looks like a bunch of issues releated to heat or lockout, so I've had trouble identifying actual light stress.

often people don't just have light stress going on when it ends up being light stress which makes it harder to diagnose the full issue(s)

Welcome to RIU
It does look a little light in color, but otherwise healthy. I would have guessed it was hungry, if anything, but with your soil it should be good!! It could be the strain maybe.....IDK.
What type water are you using?
