You don't even know how difficult that is. I have tried something like that kinda, taking pics of errs I make or things that happen because I'm lazy. Purposely running hella high or low PH and taking pics to show others what it looks like. Pics of light burn, calmag deficiencies. @Captspaulding mentioned reading your plants, he uses his nose too. That's stuff that becomes instinct over time.
Another problem with that is the confusion from different inputs. There are books that seem to contradict my opinions of plant problems. I can say to fix the PH but the deficiency chart says the plant needs Boron, or maybe copper. If the plant was PHd properly they wouldn't be asking 'whats wrong with my plant?' Nutrient lines are made with everything a plant needs with the exception of cal/mag (in most cases). Not all nutes are tailored specifically for the calmag hungry weed so we need a wee bit more. No worries tho, simply upping the Micro nutrients a touch does the trick. But people make it difficult, buying more products and overdosing calmag when they only need a little bit. Now they got more problems.
The purpose of making growing tutorials is to eliminate problems so new growers don't run into them. We've been growing weed indoors for 50 years, you may not see many problems in this forum but out in the wild the bad info runs rampant, tons of people can't figure out how to grow.
