The last week or so the biggest fan leaves on my plants are getting spots, it started on one plant but now its doing it on two. they are 3-4 weeks into flowering and are in soil. ive been checking pH and it has never went below 6.5 or above 7. Heres some pictures of the offending leaves.

try not to pour nutes on them next time be a little more carefull
That is very high possiblity, kinda fumbled a bit last time I was feeding but the damage is on the biggest leaves, pretty high up so im not too sure. thanks very much for the reply

look for bugs on the under side of the leaf. that was my problen when the leaves looked like yours.
I've been checking for bugs all the time and i havn't came across any so far but i will have a good look under the leaves. thanks very much for the reply

My guess is your using FFOF. Add Micro Nutes, cal/mag+.
The soil is John Innes No.3 mature plant compost. I've been feeding them biogrow and biobloom. i really wouldnt want to start using things like that this time as its my first grow and i wanna see what happens with the basics first, i can only learn from my mistakes. thanks very much for the reply

looks to me like you've splashed the leafs with some nute solution..
keep a close eye for the time being but i wouldn't worry yourself to much we've all done it..

Good luck fella

Im having the same problem.. Possible potassium deficiency?
i really have no idea whatsoever. i hope we figure it out before they get worse. im gonna hope its just some spilled nutes and see if it gets any better. how long into your grow are you?

I 3rd the nute splash. Keep an eye on the PH and as stated calmag is always a good idea on a regular alternating feeding schedule.
