Week 4 of flowering... Wtf wrong ?!

[BurnzyBurnz]

So I don't know wtf is wrong with my girl... Everything looks great but some of these bottom fan leaves are drying up. I don't see any signs of bugs, temperature is right, air quality is good, watering is on point... Can you suggest what's wrong please. I'm worried this may spread upwards.

Help !

My guess is too much water/too many nutrients/ not enough perlite.
She’s suffering.
This is a guess from an unseasoned rookie. Feel free to dismiss

Nutrient burn, back off by 200 ppm. I see lots of burned leaf tips.
