could just be a little nute burn.... but it doesnt look very serious and unless it begins getting worse id just maybe drop the nutes down a bit and see what happens. You arent all that far from harvest anyway
FFOF is supposed to last 30 days but I start adding their nutrients before that so u prolly just got some deficiency but don't go too hard if u decide to add nutes
I'm not gonna add any, I figure there's only a few weeks left and by the time I'll beable to afford any it'll be time to harvest them.
Not a bad choice, your end product will be flushed very well and should burn and taste just fine. U might not get the heaviest bud production, but I would rather have some clean bud than a lot of unflushed, chemical tasting bud that doesn't burn haha
