Discoloured mark on fan leaf

Hi all so I have recently noticed discoloured marks on some of my fan leaves they look a little bit shiny as well I have had a look around and all I have found is it could be thrips not sure if it could be them though plants are from seed growing in Coco they have never been outside although window has been open and it's winter here I am not sure if that makes a difference anyway would like to here people's thoughts on the matter will be checking latee with a little microscope and maybe get some pics

We're going to need photos and more information (soil, nutrients, water, ph, lighting). The more information you provide, the better your chances of getting a good answer.

Thanks will try and get a picture up later I'm growing in Canna Coco plus mixed with a few clay pebbles and the nutrients are a 2 part a and b also giving them Rhizo, zym, liquid silicon and cal/mg water is just basic tap water that's been left out over night and pH has stayed around 5.7 to 5.9 I recently just changed from a t5 to a mh that's turned down to 250w

these are the best photos i could get they actually look a bit more green but the mh was on i tried looking at them with scope but couldn't see anything

I'm gonna sound like a broken record .. I don't get all the extra fancy stuff everyone, ESPECIALLY new farmers, use.
Watering, how much and how often are so #1 important w/indoor grows & dudes it's just a plant Great Soil that is Properly Amended is going to give U great results as for water quality and environment well that's regionally specific.
The pic with all the plants together if you could take one out of there and have a daylight or outside pic I'm sure you can get a more specific answer to the "marks" on the leaves - the neon hue that pic seems to have would alarm me.

I think the pictures of just the leaves are more accurate than the one with them all together I blocked some of the light coming of the mh light when i took the ones just of the leaves and I've just been watering when it's basically dried out

Well I'm big on regular old farming methods and I have never relied on the median U use.
Also I am not a fan of Vegging under High Power lamps I flower HPS and Veg T5 / T8.
So my opinion is going to blow up your set up which BTW is bomb and don't get me wrong HID and those that have great results I give all the cred too. I suspect watering when that lamp is on could heat leaf tips ( like I said plants that young I don't think need HID ) but definitely for sure I think your either locking out mineral intake or have it wrong ... Me good old soil works and I amend it like a professional farmer. Look I learned hard lessons farming inside as well but this I know 100% for sure I get my dirt happy and the plant is happy I really don't feed the plants I let the soil do that.

I've only just put them under the mh and I've put the Ballast to 250w they was under a t5 will just change what I'm feeding and just start with the a and b and move on from there

doesnt look like bugs to me, more like water spots.
