Also you have no perlite in your soil by the looks of it? So be very careful in watering, water a bit then let the soil soak it and re water if need be

I’m growing the same strain and oddly enough I’m pretty much the same timing as you. My plants look a bit different tho. The discolouration is normal. No more nitrogen and ph should be at 6.6-6.8 while they flower.
