HELP! Leaves with dark purple stains

[bermas]

Please, some help diagnosing my plant.

Info:

Girl Scout Cookies Auto, 2º week flowering.

Medium Peat & Perlite

Growing Indoor, with bulb leds. (Like a LOT of bulbs (a grid with 16), getting 100k lux near plant, 20 cm distance. I dont know if this is a too much, but doesnt seems that its a light burn. Ive read that bulb leds are not very strong.)

Using Bio-Bizz nutrients (Bio-Grow since vegetative, and just started Top-Max & Bio-Bloom in those 2 weeks/flowering.) In the first week of flowering I put very little Top-Max and Bio-Bloom, worried about overdose. But now Im going with the Bio-Bizz Schedule, no fear, because I suspect shes is demanding more nutrientes than what Im giving her.)

I do a 'main watering' with nutrients every sunday, and an 'only watering' usually at wednesday (if I feel she need it).
Struggling a bit with temperature and humidity, but no drastic peaks.

These purple stains appeared just after pre-flowering. Its not all the leaves, but its catching mainly some new small ones. And also affecting some branchs.

Thanks!

It looks like genetics doing there thing or temps at night dropping I wouldn’t worry I’d be excited for a beautiful colour change. It looks healthy and happy to me

Hey man, crazy you said that, because the thing about night temperature was something I really was worried about, but didnt know could be an issue... I had this SAME feedback in another forum, so good to have smart people around. Ill try to chill. Its my first growth, so the slightest changes get me panicked lol... Thanks a lot!
