Offering us drips and drabs of info lessens the likelyhood of an accurate diagnosis and treatment plan. Completely filling-out the troubleshooting form saves time, and possibly your plants.


Possibly...too many micronutes.
Possibly...overspraying. Do you spray with anything other than properly ph'd water? (nutes, micro's, bug sprays or oils...)

Possibly...need the 1000w light raised a bit. (is it an air cooled hood or air-conditioned room?)
