To be perfectly frank I haven't the foggiest idea. What I do know however is when I get stuf like that happening to my leaves I don't panic and I don't do anything just water, feed and let them grow. Works for me.
I've been growing successfully for quite a few years and I have never flushed but then again that's just the way I do, it. Happy growing and soon for you comes the bet part enjoying the fine smoke you have grown.
I may be mistaken about the name but short ryder comes to mind as being a very good smoke and I would say about an oz per plant.I never way my grows i just guesstimate.
I've said it many times before who gives a shit if some of your leaves are turning yellow in flowering. As long as the bud is ok don't worry about the leaves.
I've used ocean forest for the past 5 years and have started my seeds in same. I agree with thoase who say it'as too hot, however the end result is always good. I will be going with Happy Frog my next grow just to see if there's any difference. .
I can't tell you what they are however I can tell you I get weird shit like that on some of my leaves all of the time or so,it seems and the bud has always turned out to be primo,
