Thanks for the response -

I am using a fogger to help feed the roots, which has a small red LED that is always on while the fogger is. Didn't seem to effect the last project that didn't have lamp or pump issues. Was also Auto Flower, though a different seed house, and had no issues going to flower with them.

I may take your suggestion and turn off the fogger and also make sure the box is as light tight as I can make it... then check again after a short while.

I'm willing to wait a bit to see what happens, just feels like I'm setting things back each time I have to cut the girls back.

Thanks again - mrmcr2
