Noticed the yellowing tips 2-3 weeks ago all of them wasn’t bad now starting to turn brown with a couple of leaves that have brown spots.
I am only using the big bloom and grow big never more than 50% usually less did not start any feeding until week four when they started to flower.
From what I can find looks like possible potassium and or mag deficiency. Not an expert.
Was going to start bloom Nutrients next watering tomorrow.
This is my first grow All help is appreciated.
