Leafs drooping & missing

I've recently changed the position of my light, it's now a little bit closer to the top of my plant; the top few leaf tips are drooping and one or two of the buds are looking kinda weird, the bottom half seems fine, and there was one or two holes in the leaves.

This is a nute-free grow, I water it daily and usually when the soil is dry, i've used about 1 litre of nutes before the flowering cycle, here are some pics.

The last picture is of a healthy bud

Can anyone help?

"This is a nute-free grow..........I've used about 1 litre of nutes before the flowering cycle" dont take this the wrong way, but that's not a "nute-free" grow if you added a litre of nutes. not sure what kind of light you have but it definitely looks like it got too close to the top of that plant..... if it's an HPS it needs a little more room. goodluck!

Why would you want to do a nutrient free grow? What do you expect the plant to live on if there is no food? And you added nutrients already.

The light is maybe too close, but that doesn't look burnt as much as eaten. Have you seen any bugs recently?

Can't really see many bugs except there was a few flies around the soil once, and I meant it was a nute-free grow, I only put in some, it is a HPS and I'm doing a nute-free grow because there are my first crops.

over watering maybe?
