Got a low spot in the middle of your table or are your plants on the ground?

Move your lights up. You dont need to slam em with 1ks. I keep mine any where from 2ft to 3ft above canopy. I get big ass rock hard colas every time

Like I said... check your table for a low spot in the middle. Water will be pooling there and messing with the plant.

If that's not the issue, raise the light(s) as suggested.

Hope that helps...
