5000 is WAY too high. You need to be down near 700. I have some AP beans, but held back from growing them and glad I did. I seek a great yielder, but also extremely resinous.
I blog on 420 magazine, but unfortunately their server seems to be down. When it's back up, I suggest finding my thread there titled "How to use Hydro Buddy and Mix Nutes". I used GH 3 part for years and always saw leaf damage, but never really knew how to remedy that. I now mix my own nutes from salts and every element right down to the trace elements are intentionally targeted to produce the most favorable result. Each strain has slightly different needs, so when growing new strains, I quickly learn which adjustments need to be made and make them. I now grow perfect cannabis. Well, let me more accurately state that, I now grow with perfect nutrients so the plant can produce the best possible results.
