What did this damage? Pics included.

Does anyone recognise this kind of damage? Its done by a tiny slow moving translucent bug that usually nestles itself anywhere directly beside the main vein of the leaf on the underside. I fear it could be spider mites but ive only found them by themselves and i dont see any eggs or anything. The bug is about the size of these two dots > ..
Is that too big to be a spider mite?

As you can see the leaves have had the juices sucked out of them by something tiny, it isnt chewing them.

Maybe this will help me get a reply

1) PICTURE OF PLANT *** VERY IMPORTANT *** - above ^^^
2) Growing indoor or outdoors - Started outdoor, brought indoor to flower
3) Watering schedule - Whenever the soil is dried up, every two or three days
4) Growing Medium - Soil
5) What stage of growth - Day 35 flower

The more information you put in here the better diagnosis you will get. - YAY

You have some nutrient burn. Whether it's burn AND bugs, idk, none of us can really diagnose a bug problem easily without seeing it in person or maybe a web or something that was created that is more unique and could help further identify. I just noticed your tips are burnt in the first pic, prob from too much Nitrogen, and then on the 2nd you have similar burns around the edges. So idk if I'd blame an insect for those at first. Again, maybe some.

If that were me and I thought it could be both, I'd flush the soil with water only and not feed for atleast a week

AND

Spray down with an organic pesticide containing one or a few of the following: Neem oil, Peppermint Oil, Canola Oil, Sesame Oil, Cactus Oil, Thyme Oil, Rosemary Oil

Wanna show some bud shots? If you're about halfway thru flowering, I'm curious how much bud development you've got and what they look like. This will help determine burns/defeciencies as well

Hey thanks for replying Mazar!

Im pretty sure the yellow tips and edges have been fixed, the leaf doesnt repair itself right? I was actually giving them way too much nutes until 2- 3 weeks ago, i made the mistake of following the biobizz schedule but i found a new schedule which seems to work. I had to flush my soil before i brought them into flower because the ph was WAY off, probably because i used alg-a-mic which caused a build up.

Im pretty sure that the eaten out parts are done by that little bug but im finding it hard to find neem oil Ill see if i can find some of your other suggestions, is it ok to spray a flowering plant?

If you wanna see some pics, check out my grow journal: https://www.rollitup.org/grow-journals/373287-first-grow-600w-vegged-two.html

It only contains pics upto day 26 cause i havent updated it, i wanna see a nice difference in the next update

Here's a nice pic from day 31 (havent taken any pics in a few days)



Thanks again

I'm not so convinced its a nutrient burn. Burns usually have spotting or curling edges, this pattern of the affected area kinda looks like some sort of infestation.
