EC means Electrical Conductivity. Nutrients are salts and the more salt there is in the water the easier it is for a current to pass between the two electrodes in the meter's probe and the higher the EC. It is also expressed as parts per million, PPM, which is the type I use. I don't use it for nutes I feed my plants in soil preferring to just go by mls/L for them and using the pen to test my nute levels for DWC.I don't know what EC means. Do i ph the water? Thank you for all your help. the flower tent plants are starting to look bad.
Forgot to mention that you should pH your water if those aren't pH Perfect nutes. I figured they all were now so they either didn't do it with those or you have real old bottles of nutes. I almost bought a 10 or 12 year old jar of Big Bud powder last summer but knew that Dr. Hornsby's name hasn't been on the label for that long and told the guy it wasn't very nice of him to sell old stock like that at full price. He left it on the shelf.
pH 6 - 6.5 should be fine but wait to test until the nutes have all been mixed in and it's sat for at least an hour so the pH can stabilize. Overnight is even better. Even better is to have a small air pump bubbling in the water to load it up with as much oxygen as possible before giving it to the plants. Will help stabilize the pH faster too.

Holy crap!
Those first plant pics with the droopy ones. Flushing reduces the ppm drastically and I had a similar thing happen with a revegged girl in DWC when I cleaned out the tub and ran RO water with peroxide for 24 hours then added a ll the nutes. Kind of a shock where they reverse the flow of nutes from the plant out through the roots. I sprayed her really good a couple times a day with RO water to keep her hydrated and after about a week she started perking up and went on to give me a few oz of good bud.
The 2nd batch of pics I don't know WTF is going on. Weird mottled looking chlorosis thing happening. If you flushed with water right out of the hose maybe it's something in your water. Chlorine, chloramine. Not sure. Did you feed those ones too and how much?
How much all this might have to do with the initial overdose I'm not sure but mist those girls good and get under the leaves where the absorb the water best and ride it out. AN makes a product called Revive for situations like this and it's supposed to work pretty good if you can get it. My guy was out when I got a lot of stuff last fall. Never used it but thought it might be handy to have around.
Good luck!
