Put your light up asap! You are cremating your plant bro. Light to close to the plant causes this

Strange Shape
One of my two Super Lemon Haze Auto plants is growing just like this. I didn't use nutrients for the past week trying to see if it returns back to the normal shape. The other plant is growing fine, also watering with no nutrients in a soiless. Any ideias on what can be happening?

Spraying the leaves
While I was checking my plant I saw these āblack stainsā like the plant is āhalf-bitten/scorchedā.Is it possible to burn my leaves and create this effect after spraying them with nutes. Blacks spots were created today after I sprayed them and there were drops on leaves for hours

Please help! Contorted, darker green and slightly shiny leaves with spots.
Do you think this looks like a nitrogen toxicity issue? Is it likely because I made a mistake using mainstream potting mix with slow release fertiliser in it? If so, will a flush or multiple flushes help, or should I transplant to better quality, organic soil? Thanks in advance!

Leaf mutations in Northern Light Automatic (RQS)
Hello. Could this leaf mutation in Northern Light Automatic (RQS) be dangerous to the plants? What could it be caused by? Could this be caused by too much light for the sprout and the Top Crop Green Explosion fertiliser? The leaves grew very strong in a few days after fusion.

Too little calcium in early flower?
Iām in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)

Brown patches in leaves late into flowering
I noticed some brown patches on my leaves late into flowering, almost as if they were dirty. I started flushing a week ago. Is this normal or should I do something? The plant is almost ready to be harvested, maybe one week more.
