While we're recommending light meter apps, I'd like to suggest Photone.

I agree with Whitey.
We could guess and throw numbers at you. But your best option is a PPFD app . And tentbuddy I'd recommend since it's easy to use and has another function for DLI And VPD on app .
That's the best thing honestly your phone can be used , it's not 100% accurate but it gets u in the right ranges.
Tentbuddy , is the best option for u here.
Best of luck!

Download tent buddy it has a PPFD reader that uses your front camera and it will give a pretty good idea where you should have your lights.. but if ya can't about 14 to 16 inches would be where I would want to be

Lighting cycle for VEG stage. Is 24x7 OK?Hi,
Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED
Thanks,

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent?
I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.Other. General questions

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

When did the flowering start?The LED panel, after switching (Ts600 Mars Hydro), stayed slightly on even during the dark hours. I managed to fix the issue, but I'm not sure how to count the flowering period. The plant had shown some differentiation, a few pistils, and a bit of stretching. What do you think?
