Weird Browning / Yellowing Day 50 From Seed

Hi all,

I'm having some issues with one of my plants - seems to be spreading to the other three; there is a significant amount of yellowing / brown spots that have appeared on some of the fan leaves - all during flowering.

Hydro grow; PH is 6.0, PPM is @ or near 1,000, res temp fluctuates from 25 c - 29 c. Ambient temp is around 75F day / 70 night.

Strain is White Dwarf Feminized Auto.

Any help would be appreciated. I am just confused - I think it may be a N or a P problem?

Thanks in advance!

(PS - First three photos are of leaves with the issues - last is of the same plants with some nice looking colas if I don't say so myself!)

Yeah, this is nute burn... lower the nutes under 800ppm and the problem should dissapear.

White dwarf has ruderalis genetics. Most strains with a bit of ruderalis in them can't take too many nutes.

Awesome! Thanks - will do. + rep, by the way. Thanks DR!
