I'll be interested to see your results. I have seen plants on the net from Fastbuds that yield well and look great. My personal experience, twice, was completely mind blowing sorry plants. First round I thought maybe my inexperience with autos was the culprit. Second round same results, different method.
I did talk with Fastbuds and they were not sure what happened either. Maybe seeds damaged in transit or exposed to something that made them grow funny. I don't know, but the results were alarming.
I grew these in promix with 30% Coco, perilite, worm castings, compost. Botanicare nutrients. 20-4 lighting with a 1k hortilux. Temps 72-75 rh45 then Rh 30 last few weeks.
Strains were LSD, Tangie, and GSC.
I hope your results are far better. I'm not trying to bash Fastbuds as they we always quick to respond and sent second batch of seeds for free. Very nice people for sure. I just can't dedicate any more time and money for this result.
