started seeing brown almost yellow little spots on fans leaving which started to appear over night. What could be the problem here ? Actually I was having potassium deficiency,so I feed them potassium like three days ago before those brown spots started appearing. Those couple little fading green leaves am afraid it can be nitrogen deficiency?

You probably tried to add nutrient on top of a already amended soil. Overferting and nutrient lockouts is the most common problem for beginners starting out, that and watering practices ie watering to much, not enough etc..
