Hey guys first time growers here. I'm in maybe fourth week of flower and I'm getting these brown spots it looks a bit worse in person.. I added cal-mag from Fox farms on Wednesday and yesterday but it's still getting worse please any advice is appreciated Sent from my NUU_A3 using Grasscity Forum mobile app
I cant say but I'm sure some of the more experienced blades will have an idea. Meanwhile let me ask you some question so they have more info: Have you checked for pests with a loupe? make sure to check the underside of leaves. what soil are they in (bagged brand or self mixed, recipe?)? feeding/top dressing anything? pot size? what water are you using? also a pic of the whole plant with pot could help.
While I haven't checked I was spraying need until I saw some buds and I'm using recipe 420 emerald triangle seems to be pretty good has microbes and I haven't seen anything wrong using only water
