Rives,
Yeah. Where IS SeaMaiden? I always think of her in nute discussions. I think someone ran her off. I seem to remember her getting into it with I don't remember who, but he was out of line.
That's a loss. -granger
when in doubt, flush with 1/4 strength nutes. A well-balanced base nutrient in the right ph should provide the plant with everything it needs. 1200 ppm is pretty strong, unless it is a strain you are confident can handle it. I regularly feed about half that and do just fine, no need to flush ever except at the very last week or so.
I never understand why people say to flush with half strength nutrients. the whole point of a flush is to correct an issue, and if you have over fed or have the wrong nutrient balance in the coco, you really need to clear it all then start from stratch. you should flush with ph'ed water to correct the ph and clear out the nutrients, then when they need watering again, start adding the correct nutrients at the correct ph.
Guys. Easy fix. You're having PH lockout. Adjust ph to 5.8-5.9 range, and get rid of all that N in your mix.
Anyhow, no need to throw the plant out, just a simple fix?
BTW - No one poisoned your plant... lol, nice thread title dude...
