Lock out or Starving?

I am rather new to this ie growing and forums but here goes. I am using house and garden and try to feed every other or every other other time but most of the time go a bit lite. (ppms at 750 apx) I have a few plants that are having major issues. They look like they are starving but are they starving because they need food or that they are locked out. I just got a ppm meter and even though the plants look identical one is testing its run off at 1800 and the other is showing run off at 250. This all occurred from a ph gauge that was not working. Near as I can tell for maybe two weeks. When I discovered it, it was somewhat too late. The plants that had really high ppm I flushed and the plants that were low I fed. Is there a rule of thumb on this. I am growing in soil so at what ppm do you need to think about feeding and at what point do you think you have lock out. Is it normal to see the ppm's high and the ph go really low. It seems as if these two factors are inversely related, so do I panic when I feed them to see the plants ph go to 5.8. I have a big problem on my hands. Now I am doing all the plants individual and testing each one at each watering so I know what the run off is for both ppm's and ph. Have any idea how long this is taking. Im dying. The leaves are lime green on the sick ones and have brownish grey spots on them, they are curling upward and look terrible. The other previously healthy plants are now showing begining signs of grey spotting on the leaves and I just do not know what I am doing wrong. I am in three weeks in bloom and am afraid I will get hermies if I cant get it under control fast. Am I over or under feeding or due to the fact that some were flushed is it both. On top of all of that now the room has a slight sweet smell to it but occurred two days ago and coincided with when I started using vermi T is that normal or do I have root rot to boot. Help!!!

Holey shit that's long.... i THINK MY CLOTHES are out of style LOL. you will find short and pic's workes better.

no matter what is wrong here is what to do. Flush with a 25% of what they recommend on the bottle, not what you think. Make sure you get some good run off. This will reset everything and all should be ok IN 3 TO 5 DAYS.
 
Are you by chance using RO/DI water?

I locked all my plants out trying to PH RO/DI water. After really digging deep, I found that hydrogen can't be tested properly when De-ionized with out adding a chloride.

This caused me to PH my water way too acidic and blew my grow by locking all nutes out.
