Whats wrong with these plants?

I've been battling pH issues...the pH keeps wanting to climb so I have had to keep adding pH down to keep it around 5.2-5.8. I had to do a nute change within 9 days because my TDS readings were off the scale. I'm using GH 3-part and cal mag.

I'm hoping the nute changed helped...the newer leaves look ok so far

I have one plant that is unaffected and seems to be doing fine

looks like mites at a first glance, but the high ph is telling me that you have a calcium problem. you need to keep your ph under 6.2 or calcium will be locked out (i think that number is right, i'll double check in a minute)

looks like a severe ca deff, probably from lockout. i could be mistaken, i can't find a pic that matches perfectly.

fix the ph, and it should fix the problem.

weird patterns. I would think fungus or some kind of other growth would make those patterns. But then again, I have never seen fungus on weed plants.

Do you have one of thos 60X-100X microscopes from radio shack? If not get one, and look real close at one of your leafs and see what is going on, up close and personal.

Hi there Kugine,

Did you figure out what that was? If not, could you get a close up shot. Maybe even put a magnifying glass over your camera if you need to. I am dieing to know what that was, or is.

We think it was calcium lock-out from me keeping the pH too low. I was trying to maintain 5.2 but since I moved it up to 5.8 it seems to have eliminated the problem. The old leaves never returned to normal but all the new leaves look good now.
