Seeing those first few pictures of the leafs, my initial thought was minor light burn. Then I got to the lower photos and it started to look like some nitrogen issues. Do the most affected leaves pluck off easily?

Hi, they do pluck off easily!
It is quite clear to see how important nitrogen is to your plants and why a deficiency could be so damaging. Luckily, nitrogen deficiency is quite easy to detect if you know what to look for.
One of the key signs of nitrogen deficiency within your weed plants is yellowing leaves. The older and lower leaves on your plants will start to become yellow, wilt, and drop off. This is because the younger leaves higher up the plant will start to steal the nitrogen from these older leaves. The plant prioritises higher leaves as they receive the most light, contributing greatly toward photosynthesis.
This may not always be a concern. It is normal for these lower and older leaves to start becoming yellow and dropping off towards the end of the grow cycle as nitrogen is diverted toward the buds. It is time to worry when your plant’s leaves start to yellow and drop off rapidly during the vegetative phase. If this yellowing starts to move up the plant in a climbing manner, then a problem is most likely present.
A solution to this problem is to provide your plants with a balanced nutrient product. There are many formulas available that provide an array of key nutrients to your plants, making sure that nitrogen levels are kept at a healthy level all the way through the vital vegetative phase.
NITROGEN TOXICITY
Some novice growers may be shaken at the sight of nitrogen deficiency symptoms, causing them to go overboard when adding nitrogen to their soil. However, be forewarned: the pendulum can swing the other way when it comes to nitrogen, with too much also causing a problem in plants.
When a grower accidentally puts far too much of the nutrient into their soil, it can cause the phenomena of nitrogen toxicity. During the vegetative phase of the grow cycle, it is rare that plants will develop nitrogen toxicity unless a huge amount is given to them. Nitrogen toxicity is more common during the flowering phase, as plants require lower levels of nitrogen at this point. Symptoms of toxicity can manifest in shiny leaves, much darker green leaves, weak stems on plants, much slower overall growth and clawing of leaves. Clawing is a typical occurrence that involves the tip of leaves losing vigour and folding downwards, resulting in a claw-like appearance.

I sux at the jewelers loupe! Also I still don’t feel like i have any clue when the plants will be ready, except for time. What should I be looking for?
Also, the big plant looks great, big bud sites and white powdery leaves,pic 1 & 2. However, the unhealthiest plant has amber hairs what would that be, pic 3?

I know it’s nerve racking your first grow. That’s why we are all here to help do this together.
you’ll get better at the loupe. I’ll try to do a helpful on how I do it tonight.... unless @Backlipslide already has one ?

Lots of microscope apps for phones work great
I got this also, plugs right into my Android phone

A new day, new problem. I saw two ants in the bedroom but not the grow room. It has been warm but I have been keeping everything clean.
I readDiatomaceous Earth works well coupled with cinnamon. Does it work? Is seems cruel to cut the bugs with the DE and let them slowly die
Any suggestions?
