Brown leave spots

plants needs flower nutes, reminds phosphorus necrosis, leaves a bit pale too. some wrinkle : would say you overwater them, that could play with pots ph and make nutes not avaliable, make sure you have wet/dry cycles, now looks like you water them too early, while pot was still a bit moist, aka overwatering. make sure ph is in 6.2-6.5 range too, watering regime and ph are most important things in soil grows.

some signs of overfeeding, but checking your diary all is going well..
