Check the underside of your leaves carefully. Do you see any dots, eggs, or bugs? Are you using any nutrients? How long have these plants been in those pots? What kind of soil?
Is there adequate drainage? Have you checked the ph & ppm of your water?

No bugs or eggs only the brown spots on top of leaves, I was told not to use nutrients at this stage just cal-mag they have been in pot for 4weeks I'm using root organic formula 707 my pH is 6 don't no what ppm is?
