Light, or nute burn

[Lp_jr]

Just checking my logic with the group. I've noticed some burn on the edges of some leaves and some brown spots on a couple of leaves.

Pretty sure this is a PH problem, but just wanted to check with the collective to see if it may be light burn.

Looks like a little nute burn, but not too bad actually. Look like ruteralis to me, it's an auto? What's the age? What lights do you have on it?

Just use some filtered water flushes, and you should be fine.

Is that the original buckwheat in your avatar ? Don't see much of him or alfalfa or stymie or sparky around anymore .....
Brings back good memories.....
