Nah, we all learn from our mistakes lol. It's good to document flaws so it may help another grower, I believe my symptoms are from using mammoth p, I used it as directed on the bottle, and I believe the soil and nutes combined didn't have enough phosphorous and the mammoth p was having the plant eat it all up too fast, so she's either too much or too little P. I'm guessing it's not enough, because I had this same problem with skywalker and assumed a P toxicity, and I now believe it was a lack of P.
