bad end to first grow?

Hello Friends,

This is Day 26 of flower on this NL-auto on the left (please ignore for now the Candy Land Auto on the right).

Based on PH, PPM readings and looks, I've been battling calcium deficiency/nutrient deficient/PH since about day 25 from sprout in FFO soil, - which is when I started adding the CalMag and initial nutrients to my RO water. (I know I was negligent and late and yes I am sorry and I deeply regret it.) I believe I underfed those nutrients for the following few weeks ... So here she and I are now ... and I have some questions I hope you folks might help answer.

1. Based on the damage (much of which was pruned away last week), is this going to be bad bud to smoke? (taste, potency, etc.)

2. Given the age of this plant, and given the long-term nutrient deficiency when exactly should I flush and then stop watering?

3. How do I use this Carson Microbridge Plus 60x-120x LED Lighted Zoom Pocket Microscope with Aspheric Lens System to look at the trichomes? Do I use tweezers to pinch a tiny bit of bud off and look at on a flat surface? Or do I push the thing all up onto the colas? Something else?

4. Does this story have a sad ending? Thanks so much for any helpful advice you all can share!

Looks like a textbook case of light burn. Which grow light are you using and how far away is it from the top of the plant?

@aarcamp Ok so it's about 16" from the top cola now? That means it should be getting ~700 PPFD dead-center of footprint. I would see how the plant reacts to that. Unfortunately the impacted leaves with brown spots won't recover but you shouldn't see any further damage.
