Aqueminianswered grow question 3 years ago Just feed them a little more Nitrogen, but keep heavier on the bloom nutrients. I did the same thing to my OG Diesel Kush autoflower if you want to check it out. I stopped the grow nutrients to early and it turned lime green. It's just now starting to swell the buds. It will be ok, just don't overdo the nutrients. Nutrient burn can hinder your plants more then unfertilized at this point.
That's just my opinion though. Good luck to you and your grow!
