Burnt tips and yellowing leaves
About two week ago, lower leaves started yellowing, and I saw burn leave tips, so I suspected nutrient burn. I only watered with tap 6.5 pHed water since, but the burnt tips and yellowing are getting worse continuously. At least 3 largest lower leaves died off over the period.

Hey Guys, my NL is starting to have some issues. I started off with the leaves just laying low, i've eliminated lack and excess water, and it's not temperature related. I did a small flush 3 days ago and things got worse. What do you guys think?
