brown spots on leaves
|
|
first of all, these plants are indoor & I just switched them from regular shop flourescents to 8 buld T-5. I had just lowered the lights to 12 and sexed them them started with the T-5's @ 14 hrs, going up 1 hour a day & I am at 21 hrs. now. My goal was 24 hrs.
I watered more w/ 1/2 dose fert. every day & added magns. in form of epson salt since my fert. didn't have any.
The leaves have brown spots that ARE not on the top, neccesarily and they are more rectangular shaped - not round. I am going to try to add these pictures. I am at a loss as to problem.
