Leaves getting brown spots in middle

[FreddyDeeb]

So far, I can't tell what's wrong with the 3 mom's I've got. There are 2 strains, 2 are skunk and the 3rd is strawberry cough. I started noticing spots on several leaves last week. Here's some bad photos of a few from a few days ago.

I'm using technaflora products, BC Grow, BC Boost and thrive alive. I keep the pH at a steady 5.8-6.0. Using hydro/DWC/bubbler technique. Recently put up a 1000W digital ballast w/ agromax bulb. All three mothers are in their own 5 gallon bucket. I'm using hydrotron as a medium. They've been in vegetative growth 7 weeks this Sunday. The room is a pretty constant 80. Do the BC boost and BC Grow have a history of having certain deficiencies? I did take 8 clones off each and removed some of the larger canopy leaves, could that cause a bad reaction? Any insight would be appreciated.

hi freddydeeb did you findout what the brown spotting was i think i may have the same issue and cant sort it

first thing that comes to my mind is calcium deficiency. It's too late for freddy but Are your ph levels low shadrack? ph levels under 5.5 can cause the plants to lockout calcium.

 

[Racefan]

get some cal/mag. It will replace the calcium and magnesium your missing. But first find out what is locking these elements out. Check ph.

 

[Stix]

would you recommend a foiler spray or put it straight into the nutes racefan?

I believe foiler spray will work quicker. But you should dilute it to 25%?

heres a few pics
see what you think im leaning towards nitrogen lockout du to crapy ph meter and it being too low

cant uplaod any pics is it because i only done 1 post

I have the same problem spots on the leaves and some leaves are curled too. My Ph is so high 8.0 I cant bring it down any suggestions?

Katayama: what did you try to bring the PH down?

 

[Aratilis]

im trying to bring it down, i transplanted them thinking my soil is the problem so having a new mix for the transplant would help, it did by a fraction only. I tested my Ph meter if its accurate with calibration solution and its pretty much spot on. I always Ph adjust the water I gave them and I just did a test a while ago; trying to find out whats the ph of my ph adjusted water with nutes and to my surprise the Ph was lower than plain ph adjusted water.

Nutrients are almost always acidic so that would be expected Aratilis. Just though I would throw that in there, lol. Old post, probably noone will read it.
