Damn man, that sucks. I've never had a hermi, ever. It could be because I use store bought seeds/just get lucky with good genetics/the way I handle the ladies just gets er done. Did you do something during the growing process that could have stressed them? Light leaks?

Personally, I don't even TOUCH them or move them at all, except for when transplanting (even then I make that process as fast as possible and gentle). Probably just genetics though. Your next grow should be actual strains from a breeder. You have the process down enough to risk some money on beans.

If your 3rd one doesn't turn hermie, I wouldn't worry about the size. Sometimes the biggest yielders are the smallest ones.

As for your water, I have no knowledge at all about store bought water. I don't drink my tap water either (it's terrible) and just ph adjust it, and it does just fine. Besides maybe some lime build up (which I've never had noticeable deficiencies from) tap water IMO works just fine.

Good luck on your last lady. :stoned:
