Is it on the leaf itself or is it a layer on top of the leaf?

White/Yellow snipes on leaves? (13th day of growth from seed)
I noticed a huge change in my plant leaves in less than 24 hours. The leaves look like they are getting burned out. What is happening? I'm uploading pictures to see the problem and also the growth conditions. I'm watering once every 1 or 2 days (PH = 6.0). Not using nutrients yet

Is this a Magnesium Deficiency?
Hi all, Day 98. Northern Lights. 1 of my 3 NL girls looks to have a bit of a Mg deficiency. I'm close to harvest so not too worried however it would be nice to have a confirmation for future grows/learning as I'm very much a noob still. Can anyone confirm/correct me please

Leaf colour help. Hi all. I think there may be a problem with the new growth on my plants. They are 10 days into flowering 12/12. They look like they are too light. They veins are much darker giving them a stripey look. I had the light very close to them when it started. ?

Leaf striations
This auto has formed light green striped between the veins of the leaves. This happened with my previous grow also. The striations appear first on the bottom leaves then previously worked it's way up the other fan leaves. I use compost, haven't been overwatering & no fertiliser.

Deficiency?
What is causing this deficiency? UsingProMix HP, top dressed with worm castings, and foliar spray with Epsom salts. I think it is Fe/Mn/Zn deficiency that looks like magnesium deficiency, and it seems to happen to all the plants at about this age. Mega Crop and kelp to fix?

Is this a symptom of spider mites or something else?
Is this symptom caused by spider mites also, or is this a different issue? There is pale green/loss of color along the veins of two leaves. I’m aware of my spider mite problem, but want to know if there is another issue or just more symptoms of the mites.

First week and never had little plants struggling so much to grow. Please, read my comment about the first week to a detailed explanation of the problem. The question is, what else can I do, except from waiting? I don't want to over do (again)

A few of the leaves started to get yellow spots along the veins. I was pretty sure it was nitrogen deficiency so I upped the nutes a little. Over the next day or so, 2-3 different leaves started to curl down at the tip. Is this too much nitrogen?

Clones are degenerating, help!
It started with yellowing between the veins and I thought it's Mag deficiency, already ordered Epsom Salt. Today many leaves started dying. Is it just Mag def. or something else? Shouldn't be over watering.
