If his bud tasted fucked up, it wasn't because of MG.
...and this is the same conclusion I have come to. Ultimately it looks as though we can compare it to eating fast food vs. Home cooking. They both get nutrients the body needs but it is all in the eye of the beholder.
In my case we have taken new SLH clones and they have gone into the garden. This time they have a 100+ day schedule anticipated. Previously they were being cut from 65-85 days and the desired intensities weren't there. On a whim I have now allowed 2 different phenos to go to day 99 as of today, Trichs still clear. Plan is to see how long they take to turn. If it turns out that this strain is not going to give me what I want inside 120 days..... Its going to get scrapped.
