Nute burn or a deficiency

[Cannabutterred]

Hello all, I have about a 2 month old plant that I've topped once and lst a little bit. I had a slight overwatering problem when she was a seedling.

She is still rapidly growing and I only have a 2x2x5 so I'm thinking about flowering soon, like withing a week. And some of the leaves have burnt tips and discoleration. I water with distilled water 3ml of cal mag plus alternated with distilled water and fox farm grow big 8ml.

It seems I'm seeing signs of a cal mag deficiency, but it also looks like nute burn

Damn, wish I could offer some advice brother, but I'm not there yet. Gonna follow this as I've seen similar issues with mine recently. Good luck!

How close are your lights?

It's a 100w hydro mars, and it's 16" from the plant

One thing about using distilled water is that it has no pH buffering capacity. Its pH can be influenced strongly with more minor inputs (acid or basic) than tap water. Are you measuring pH going in and if so, how? Also looks like you might still be over watering.

Raise your lights to 32 inches, your plant is burning.
