What can I do here?Is it an issue. Will this spread if I move into veg room? Should I just axe them,and start over? thx
YES IT WILL SPREAD.. FUCK Powdery mildew, its such a bitch. Kill the clones or sulfur burn/milk spray. Sanitize your clone area too. Also, it never dies in the plant you only keep it at bay.
Powdery mildew is something that is VERY difficult to get rid of. If its real bad, or you can't get rid of it, I would suggest Eagle 20! That shit will take care of it in no time flat.
