200k lux?

[HuffnPufferfish]

so i borrowed a phone and took it into my box, and the lux meter apps gave me 180 000 - 200 000 lux
not such a bad output for a few fluor tubes and some leftover leds

however i see numbers around 50k to 120k tops online..
so is that why my tops turn white/pink?

cxb3590 3500k @1050ma, @220k lux the leaves get exhausted very quick, by end of flower i had not a single fanleaf green, all were crumbled and dried
next run i will try and reduce to 140-180k lux... most frosty crop i have ever had with over 200k lux and 22°C average
