Could my plants be suffering from genetic defects due to cross polination of 'sibling' plants, ie. 'in-breeding'?. In the past, I've had deformed leaves on seedlings, which, I know are the offspring of sibling plants. Now I bought seed from a dealer, but see the same problems. However, other seeds I had, have produced healthy plants in the same growroom. What's happening? Can genetics cause this problem? Can unscrupulous or inexperienced dealers pass on 'bad' seed? I need a basic lesson here.
Twisted leaves? What king of defects are we talking about? Usually seeds from a reputable seed bank will be fine. A lil variations in the f2s.
Thanks for response. The new seedlings look a real mess. Irregular sized and shaped leaves, twisted, stunted, ragged-edged, discoloured. My growroom conditions must be ok because I have other healthy plants from different seed stock. I guess, I just want to know if genetics can cause these problems. I dunno how it works in plants. - thanks
