What's going on with mk Ultra? It gets Neem every 2-3 days, and I have tried to keep pH down to 6. This has been going on since I got the clone, and it continues to happen. The pink kush (last pic) has a few similar spots.

Your killing it by hitting it with neem every 2 to 3 days. Its hard on plants with 1 spray, let alone multiple sprays. Only to be used if you have pest problems. I use a few drops of dawn soap mixed with water to kill bugs.
