you have low potassium diet maybe?
maybe, i've been relying on the potassium in the molasses, which is a pretty good source of potassium
i have used wood ash in my previous grows in varying amounts
didn't seem to make much difference, one way or the other, so i didn't use it this time
but different strains have different quirks on their feed, so it is possible
the quirk with the PPP is for every fan leaf that yellows up, i get a bunch of green leaves on the colas
which is normal for PPP, actually kind of a pain to trim
but thanks for the suggestion, i had been thinking about the K level myself
i will probably ride it out as is, and see the final tally, a good yield would imply the nutrients were adequate
