DrJynx86answered grow question 4 years ago If you feel they need a little bit more, maybe they need it.
But without pictures it's difficult to say, and it's really easy to mess up.
I won't recommend it, I try to use all my nutes at 50% from start to end, coupled with good organic soil and own compost.
If you really want, you can try, get the experience and keep it for your next grows, if you increase the dosages, do it very slowly!
Happy smokes!
