Is this nut burn? (first time using nutrients)

2012-01-21_17-46-06_289.jpg2012-01-21_17-45-43_709.jpgright now only one of my strawberry cough plants has it. I just started ph ing my water and found i was probably locking all nutes out for a while. It showed up on all the clone plants, not the seed ones, and has gone away on all of the other ones except this one strawberry cough plant. it has made its way from the bottom fan leaves and has started to show on all the fan leaves now. It has gotten alot worse than these pics but i already cut those ones off. any ideas or suggestions on what i should do?

i once had nut burn when i went to thailand


but no that doesnt really look like nute burn, the leaves usually curl up at the tips first, its probably a deficiency

Also is the new growth fine? I know mine started doing the same thing from over-watering. Started letting them dry out a bit more and all new growth was fine.

bro you need some cal/mag cal/mag problems usually appear during the flowering stage this should fix you up and you can get it at a hydroponic store or on lineDSC00570.jpg
 
no theres no critters. haha i was looking under the scope and it just looks all fucked up. its a strawberry cough clone, i have another from the same mother that has nothing at all, it never did, they are in 5 gallon buckets with a soiless mix, i ph my water to 6, but i just started that 4 weeks ago, before that i was using de-chlorinated water probably around 7.3. ya dumb i know but i was using grow and micro the whole time and the plants probably werent getting any of it. i have only been watering them like a gallon once a week, they dry all the way out to around 2 inches.
