i see a little tip burn,you said you checked with new meter,did you check it wit calibration solution?
if thats soil you want 6.5 going in and buy stage of growth from looking at them should be around 750 to 900 ppm ,you have no info about your grow get more help letting loose with it,do you have a ppm meter?
what do you mean you dont use water.No meter I dont feed in water. All nutz in soil. Have a mixture of stuff. I burnt the tips a few weeks ago was messing with the ballast bump it up to 75% and left for work came back home and some of the tips burned and curled up temp got over 92 and humidity dropped. If u zoom in on the lower fans u can see the spots in not home at the moment to get close up pic. This pic is zoomed in. Thank u for ur input
what do you mean you dont use water.
what do you use this is new on me
^^^^ best way to get bugs tooLooks like nute burn and Possibly bug damage.
Also leaves transpire from the bottom side and if the bottom of the leaf is resting on soil, other leafs etc. Those portions of the leaf will not transpire properly and become damaged.
ok i got you,so your scratching in as needed,so do a slurry test on your soil and lets go from there,you might be scratching in to much,sure looks like nute burn mate,tips and edges of leaves,lights and heat usally sarrate the edges of leaf with just a tad sticking up like a gators spikes if you dig,so do a slurry test easy to do,just put 1 part of your soil in a glass or cup and 2 parts ro or distilled water,stir it all up and let it sit 15-30 min,take your ph pen and stick in the liquid above the soil and below floating stuff,the liquid will give you you soil ph
White spots on veins is often Mite damage can you get close-upsGotcha will do once I get home.
Can't really see the pictures can you get clear close-upsI had to pick up some store brand water. I didn't ph it after the first watering a day or so later this started white spots on some of the fans. The water I was using was keeping everything at 6.5 this new water testing the soil is at 5. I ph the water to 7 but hasn't dried out to water it yet do u think this will bring it back up and I know I need to check the soil with the water that I'm going to use now.

Does this look like what's going on?

That's not caused by pH, that's Mite damage, as mentioned above. Unfortunately you have mites.Yes just got home.

I don't have any product recommendations, search "cannabis mites" and find some options that way or maybe others will have input, however if I were you I wouldn't wait long that's a fairly substantial infestation and it only gets worse, and fast
Ps. Neem oil does not work
They are a real bitch I’ve had some success with Azamax you have be diligent!If it's mites, which it looks like it is, you can organically solve the problem with "Amblyseius swirskii" predator mites or lady bugs.
If you have to wait for insect delivery and you are NOT using living soil or organics, you can slow the progress by picking off infested leaves and spraying the rest of the plant with a hydrogen peroxide and water mixture (plenty of recipes if you google it). Just make sure the plants are dry before releasing your predators.
Mites are a bitch, good luck!
You might be right, I think old school might have hit it on the nose. I've never seen this that wasn't Mite related but check this..
White specks on cannabis leaves along the leave's veins and midrib.
From looking at your pix, I can make an educated guess. It's either the following and/or your PH meter is way off. when your environment isn't right indoors, such as too much heat, the plants aren't able to uptake food in a balanced manner and nutrients compete on a molecular level and are left...www.thcfarmer.com

Can you take some pictures of the underside of affected leaf
