Have supported several strains over several years including one for the past 17 years with mothers and clones. Nothing has changed for about the last 10 years. Same location and indoor set up. This one Romulin has historically produced baseball sized flower. Bulbs are strong and changed yearly. This same strain is now acting healthy but just not getting the size that it used to. It still tests at 19% so the strength hasn't changed. Taste hasn't either. The product has just decreased. I always thought genetics doesn't change but now after 17 years on the same one I'm starting to wonder if is "worn out" Anyone have a theory or similar experience?
