That SHOULD not cause them to "hermify"...lol...yet it has been said that some plants just turn hermie if you look at them the wrong way. Some genetics are just stabler than others.

Is the reason you are worried because you don't have any more room to move the lights up? That could be a problem depending on how far along you are in the flowering process. The will grow more...and if your light is very hot (I don't know if you mentioned what kind of light you were using), then they will get burnt.

If you have horizontal room, try scrogging or LSTing your plants horizontal to maximize that space while you avoid growing up. GOOD LUCK! :thumbsup: Post pics of your 3 lovely ladies, please
