hi fellow growers

I've noticed over the past 2weeks a few leaves on my Barneys Blue Cheese from seed, has weird leaf markings an I can't seem to pin point issue as the girl is growing ok!!

Canna coco
Canna nute line
Mixed light spectrums in room from CFL to LED
Temps 73-77
R/H 60-65
Watered everyday with pH 6.0, EC 0.6 with tap coming out at 0.3 an ppm around 500..

Any help would greatly help!! Thanks

Thanks for your reply guys! I've upped her dose to 1.0 ec with tap water at 0.3. Although you say up the nutes can I ask how you came to think it was nutes?? I did a lot of forum reading to find something like this but couldn't!!

don't trust my diagnosis, wait a day or two and see if someone else has a better or more accurate suggestion. i looked at some pictures and it looks like the pics i saw.
one thing i can suggest, don't stay at 6.0 ph forever, its a good idea to bounce around within a safe range, Ca. is best absorbed at 6.3, and while most charts will show that almost everything can be absorbed between 5.5 and 6.5, i've found that if you stay at the same ph all the time, your plant will end up having deficiencies

Ok great! I do play around with ranges! I tend to go 5.5-6 when there young an as they get older I go up to 5.9-6.1.... I must say I'm reluctant to go over 6.2 as I'm in pure coco an from only what I've read 6.2 is top end coco range!! But I know my girls drink a lot of cal/mag an that's fed at ph5.9-6.1 so if you say 6.3 is better for Ca then I might be able to use less ca/mag if I up the ph so they absorb it better!!

read the back of a bottle of cal-mag....ph to 6.3...it might not be that important, but they thought it was worth mentioning on the bottle

Yeah man that looks like TMV, I've been compulsively researching it in fear of my own garden and sadly your plants clearly look infected. Don't touch it with any of your other plants and wait for more signs, if it infects the other plants things will get problematic af.

Personally, I'd feed a little and see if she grows out if it.
