well they were perking up. Actually the two are doing goo...it's this one problem plant...

Pics 1 and 2 are leaves that are still on the plant.
Pic 3 are leaves I had to cut off
Pic 4 is a leaf still on the the, but a little higher up. (all the others are below the halfway point)
Pic 5 are the other two plants that seem to be doing ok, other than a small yellow spot on the one in the back.

After flushing friday and saturday nights, got the PPM down from 1400 to 700. Fed them sunday night and read the runoff to be in the mid 500's. Left them alone monday, and watered lastnight(tuesday night) with a very mild solution of nutes because I had some mix left over. Mixed some leftover with mostly tap water, had a runoff of 560PPM. Now I see this tonight. I still don't know what the ideal levels should be for my nute, coco combo. Botanicare's feeding schedule says nothing about PPM....so I'm kinda guessing here. I read somewhere on here that it takes about 3 days to see the effects of anything, so that would land this on about feeding day. Can someone please confirm if this is nute burn or not??

PH was always 5.9 going in and coming out with every watering.
I'm very confused as the other two seem to be doing ok with the same feed/water administration.

Thanks folks,
