There's good info out there...but yeah...you have to be wary.
The tasteless weed scenario could be genetics...the drying process...or the MG. Don't let him fert yer plants if he lets ya grow there.
He is smarter than me though if he's backing off cus I have yet to be able to figure out how to just run a few...
You likely have the season length there to grow more variety than I can here....but you have the mildew/mold factor that we rarely see here. In 30+ years of in/out growing I've only seen bud rot once indoors and once outdoors....and..knock on wood...I've never seen PM. Just too dry...and I don;t play the VPD game or purposely raise humidity/etc. We have a greenhouse we treat the same way. I have a dehuey that keeps things below 45% and takes the worry of all of that away. Just not worth it here...
