My leaves are in like the beginning stage of curling like a taco. I believe it is heat stress . Would spraying with water help them?( I figure the leaves are probably dry)?

too wet roots can cause the same problem, so why not raise the light and see if they recover first off?

Leaf tacoing can also be due to too high light intensity. I can get that a little from time to time and when I dim the lights down a tad that tacoing is gone.

Do you know the PPFD hitting the canopy?

I don't. I downloaded a meter app on my phone but I'm not sure if I'm supposed to have the phones screen facing the light, how far away, etc?

You can find a decent PAR meter for around 50 bucks. It won't be as exact as a quantum meter but they're close and it gives you a baseline to reference. I wish I had bought one years ago, could have saved myself a lot of issues.

It depends on the app and phone. Some aren't that bad. I have one that works fine on my S7.

I just feel like if you want to get technical and make decisions based on values you are acquiring from an instrument, you'd want that instrument to be designed to read those values properly and not just take a 'well it's prob close' reading. At that point why not just watch the plant and see if it's stressing or not and raise/lower/dim the lights as needed.

Just saying the one I downloaded works pretty damn good with my phone. You do have to hold the phone right. But can tell me if it's at 600 LUX or 90,000 LUX. The real ones are cheap enough though.

Ya, some work maybe... But I think you kinda need some exp and understand what's going on to be able to make an educated guess whether it's working right or not. I think the whole phone thing just confuses noobs more, offering a small % reliability. If they don't know, and use the wrong app or phone it can really give you some wrong values and if you're using that value as a be all end all and it's wrong...well your fucked.

I mean I don't think anyone here would tell someone to go buy a 10$ Walmart 3in1 ph/moisture/light meter but I feel like that's what you're getting when you use a phone app. Maybe it's right? Maybe it's wrong? Are you in any kind of better position knowing it could be right or wrong? Nah. We all got along fine before just watching the plants reaction and changing the height or intensity as needed. Which I think is a far better method than a guess-o-meter
I'm big on 'the right tool for the job'. I wouldn't hammer in a screw although I'm sure it would work to some extent, it's certainly not the right thing to do.

I know. Common sense goes a long ways, but it seems like it's not taught anymore, :bigjoint:

I just got lucky I guess. Because the first one I tried worked good. I've heard some people struggle, but when I recommend people to download a free one I tell them "to get an idea". And hey we can tell people how to water correctly and they'll manage to fuck that up too, :lol:

Unfortunately kids these days are glued to their phones and if Google says so then it must be true. And if the phone says so then bow to it. Member the first peanut phone Nokia? With the antenna that popped up???? And then one day text msgs were a thing. Haha. I remember the first 'color phone' I got in highschool. It was still like 8bit but there were colors instead of just different shades of grey/black.
My mind was blown.
And life before the internet.... When we had to use these things with paper inbetween cardboard called a BOOK. lol. Now I sound like a grandpa
