Hey, I've been messaging some of the experts of GC to see if they can help me with some plant problems here pic #1 is the decaying brown leaf.. (the first one that sprouted) pic #2 is the rest of my healthy plant Give whatever input ya'll can please!
Hey man, now that I have an image to go by - that doesn't look like a nute def at all. Looks like nute burn. You said you were using FFOF right? I've read that it can sometimes burn young plants. I'd definitely get a second opinion from a soil guy, but I'm pretty sure that's the issue at hand. Personally, I'd try and flush the hell out of them. Get a PPM meter and monitor your runoff. Id try and get those PPM's down as low as possible. For what its worth, on a plant that young, I'd probably be feeding them around 200ppm - so maybe thats a good target for runoff, however I'm not personally sure if thats possible using soil.
