Look real close. no Bugs Any other pertinent info? In Actually i have 3 boxes on the go in various stages of growth. I am also experimenting with led lights. This problem has been developing over the last 2 weeks. Ec is averaging 1500 when feeding with dnf gro formula. My figuring is that it is a defeciency of some sort but can't peg it. All plants are watered with the same mixture. and the problem is occuring on all the strains. however not every plant is affected to the same degree.
