What am i dealing with here. I have flushed this plant and waited until it was dry before watering. I water with a pH of 6.0-6.5, I used plain water for the first couple of weesk after flushing. Every time I let it dry back before watering again. I am currently using FOOP as a nutrient. The soil is FF Happy frog, and I have applied some recharge to the top of the soil. Any help would be greatly appreciated.

I see a few possibles. Overwatering in the past. When the serrated edges on the fans turn light yellow, it is typically from overwatering.
I also see what appears to be dried water spots on the leaves. Are you misting your canopy?
Do you have your runoff pH and PPM numbers?

I have tried misting the plant with nutrients right when the lights come on. I have not watered to run off since last flush. When I water next time, I will water until I get runoff and check the numbers.

I would think your plant is hungry. Your runoff #'s will help figure out.

I agree with @4204life. If you did a full flush and didn’t add anything back she’s real hungry

I would not mist anymore and especially at lights on. Powerful lights and the lensing effect can cause alot of other issues. She needs to uptake the nutes thru the roots, not the leaves.
Those numbers will really help us to help you. Post em up when you can.

I ran a grow using FOOP. I would water to run off and take a look at ph and ppm as @bonjoyle said. FOOP is pretty gentle, so I would feed at their recommendations. I probably fed twice a week, but based feeds on runoff.
Are you phing your FOOP mix with water? FOOP drove my ph down into the 4s after mixing. I used ph up to fix that.

So, here is what I got after watering and my runoff numbers:
Water starting pH 5.88
Starting E.C. 316 us
TDS 221 ppm
This is water with FOOP nutrients:
Starting pH 6.46. TDS 1.63 ppt
Runoff pH 6.30. TDS 2.66ppt
I’m using an Apera PC60 meter.
Is this common, for FOOP to raise the TDS level so high?

Does your misting solution contain nutes? I am not sure if that’s a good idea. My understanding is it’s best to use plain water.
Ppm,ppt,EC 
I’m lost

None of those numbers looks out of whack. I am not sure on the runoff at 2.66 ppt. My meters read PPM’s and know I need to stay right around 1000 and when it drops, I add the amount of food to get back to or slightly above the 1000.
I noticed when mixing FOOP that the ppms I thought I would be at like near 900 ppm on a 500 scale, it would actually be much closer to 700 ppm. I always felt as if I were underfeeding based on input ppms and started bumping up the nutes. That would give me really high runoff numbers. Eventually I found that using their recommendation was sufficient.

T-Ray; yeah, I’ve tried both. FOOP has a mist spray for leaf application, tried with the lowest recommendation of Nutes, but I didn’t notice any difference.
I believe the Apera meter is on a different scale. I looked it up and others on here have said it reads a scale other than a Hanna scale.
