LONG time grower, but newbie to the site. Allow me to thank you in advance for any help !!

I've been growing for 20 years, and usually I'm the one others come to for growing advice.
But I'm stumped on this problem !!
I have "blotches" on my leaves
![Rolling Eyes :roll: :roll:](/styles/smilies/icon_rolleyes.gif)
Here's the fine print ..............
-4'x4'x8' grow room. (250 cubic feet)
-2 x 400W MH(to veg) HPS(to flower) in parabolic reflectors with light-spreaders.
-4 plants under each, 8 plants total.
-450CFM blower/carbon filter, running about 280CFM after filter/90' elbow/resistance. (Room is sealed, inlet air is micron-filtered, and I try to exchange the volume of air in room once a minute or two)
-Pro-Mix soilless mix in 5-gal pots.
-GH 3-part Flora series ferts. (I use 10% under recommended/max rate)
-Superthrive & ThriveAliveB1 at mild rate.
-All meters(Light, P.H, TDS, E.C, ect.) and all water filtered with newer 6-stage R.O. system
-PH of water set to 6.7 just before feeding
-Watered every other day, when needed. Top of soil "fluffed" after.
-Containers flushed every 3-4 weeks with water/cleansing agent.
-Assorted fans here and there. Lots of air circulation
-Temps around 78'-80' & Humidity around 50%-60%
-Day 47 from seed today. Turned lights back to 12 hours on day 40.
-White Widow & White Rhino Feminized seeds from the Green House.
-I keep my room/area spotless clean.
-I'm very anal about the details, and have the time.
-I do NOT normally foliar spray.
Hmmm, what else ..... ??
P.S. Some of the leaf tips are curled down from resting against the outside walls ......
I have been using these products/conditions/technics for a long time with great success !!
-The "blotches" have clear "defind/sharp/distinct" borders, not "fuzzy", and are light tanish in color at first, and get darker brown within days
-The blotches started about a week ago, and are all on the bottom 2/3 of the plants.
-The blotches often are in kinda of a strip/line pattern.
-You can see the blotches on the under-side of leaf.
-The blotches are on about 10-20% of the leaves on entire plant (lower 2/3 of the plant).
-The blotches are spreading !!!
-All the plants are affected.
-Lower leaves are starting to yellow/fall off faster then growing new.
Everything else looks good/normal to me.
ANY help with whats going on ??
I can "guess" better than most. (I'd hate to be talked into doing the wrong thing
![Sad :sad: :sad:](/styles/smilies/icon_sad.gif)
I can't find any pics anywhere of these blotches ??!!
HELP PLEASE, it's getting worse fast !! I CAN NOT LOSE THIS ENTIRE BATCH !!
Here's some pics ......
