Stunned growth in flowering

Hi brothers, I'm doing 3 grows now. 2 of them are great. But in one of my tents I have 2 ladies. One honey bananas and one strawberry banana. The honey bananas is great. Growing and flowering every day. The strawberry banana is just the same as when I put them into flowering cycle. They were the same size at that time. Now the honey bananas is almost twice as big and has developed already buds. The strawberry banana not at all. Not even white hairs. Not even signs of preflower. And they are starting today their 5th flowering week. I don't understand. They have the same nutes. The same atmosphere. Same everything. I just really don't get it.

Anyone has an opinion about this ?

5th week of flowering and no pistils? Sounds like either a light leak or something wrong with the light timer perhaps. Got any pics?

Edit: just re-read your post... both in same tent...

or just bad genetics on that one seed!!!

So the one plant is barely growing and not developing buds after 4 weeks of 12/12? It must be the genetics.
