<Respectfully> Go read through the "Sick Plant Guide". It is a Sticky here and on many other sites. I promise you WILL find the info you are looking for there.
I like to use a 1 10 ratio mixture of fish Emulsion at this stage. I look for at least 0.04% Nitrogen. Any more than this would be too much.
Good Luck!
Dried way to fast. Paper bags dry things faster than anything. Hang it in dark until outside is dry to touch - then put in jars with no less than 24 hours between 10 min. burps. - You'll get there!
Go with FFOF and pure Ph'd water until the last 4 weeks - start feedin' slow and then give 'em a bang at the end of three weeks and flush for the last week. No water last few days, turn off the lights 48-72 and then chop it baby! Yummmmmmm-uh-E!

Fox Farm has burned plants I've seen as well. If you want to use nutes then switch to Happy Frog. It is made for nute grows.
