brown spotting on middle leaves only-stinky?

These brown spots just started showing up two days ago. I am growing in soil, which I mixed as described in stinkys beginers guide plus the addition of some worm casting, i'm indoor and am currently vegging under fluorecents that are 3.5" above the the tops, this problem is only on 2 out of 8 plants, the last time I used nutes was 9 days ago the nutes I am using have all trace minerals and the ratio is 24-8-16. it may be hard to make out in the pic bc i had problems getting my camera to foccus on the leaves but they are brownish almost like rust spots on the leave and they are only on the middle leaves of two plants.
Any in input would be great. I want to check what everyone thinks before I flush. I'm not sure on my now but I checked after I fed last and it was 6.8 and I dont know if this is a ph or nute problem or what thanks for the input.

Are you foliar feeding or misting your plants at all?
And how old are the plants?

they will be 6 weeks sunday there is a problem uploading the pics so when i get that figured out i will get them up.
I was foliar feeding but stop about two weeks ago because of yellowing and wilting and thought that might be the problem and it did stop after I stopped.

were you foliar feeding with the 24-8-16? or something else

was foliar feeding with a worm cast solution made for foliar feeding, not cannabis specifacally, and made by a company called teracycle

personally I wouldnt foliar feed, the castings are pretty high in nitrogen ferts & the ferts NPK 24-8-16 is pushing the limits

it is the NPK: 24-8-16 is use aswell

at what strengths are you mixing the 24-8-16 solutions, as recommended on the box?

Im still at 1/2 strength slowly introducing them because I burned my first grow bad and this is my 2nd attempt

I'm gonna take a stab at a diagnosis- scorch or even a fungal infection from either one of the components of your foliar feed, or the moisture itself sitting on the tender new growth.

It is only on a couple leaves of two plants like 2 on each should I just remove the affected leaves?
I put the photos up on these links since they will not upload, stinky the yellowing in the middle you can see on the one plant was already diagnosed and fixed with your help thankyou for that

Okay I retract my previous diagnosis; I thought you were talking about the new growth- that's just scarring from your previous problem in the first pic, and the others, you still have a bit of micronute def/lockout.
HAve you checked your soil pH lately?
Oh- and does that pot have a built-in drip tray? The soil looks quite damp.

I had just watered and after reading previous post of yours in hopes to gain some of your knowledge i removed them and added more drain holes to the pots
Thanks again for all your help stinky

I see your pics now and I agree with stinkyattic, you do have some defeciencies

with your ferts you should have no defeciencies, complete a soil runoff PH test

thanks I will complete a soil runoff ph test tonight

I did the flush and checked the ph which was what I thought it was pretty close to right on at 6.5 but since the flush and then a foliar feed after they have just been doing great I wish I had my camera because they are doing amazing now in the last 3 days I have had to raise the lights twice they have shot up from 8.5" to over a foot tall actually now they're about 13.5" and not stretching or getting lengthy at all so I am very happy for my first grow and thanks to all for the help so far.
